What is the measure of arc DAB?
Answer: The measure of arc DAB is 218°.
How do you find the size of an angle?
Subtract the given supplementary angle (its value in degrees) from 180 to calculate the size of the angle in question. Supplementary angles, or straight angles, are those whose sum adds up to 180 degrees.
How do you find the angle of an arc?
An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π radians = 180° π r a d i a n s = 180 ° .
What is the measure of ABD?
The measure of angle ABD plus the measure of angle CBD equals 90 degrees or a right angle. Thus, we can write the equation: ABD+51=90. Solving for ABD, we find that it is 39 degrees.
Which angles measure is equal to the sum of the measures of angle BAC and angle BCA?
Answer: ∠CBE is the angle which is equal to the sum of the measures of ∠BAC and ∠BCA.
What is the value of h h 20 h 35 h 55 h 70?
Answer: The value of h is 55. Therefore the correct option is 3.
Which represents an exterior angle of triangle XYZ?
Exterior angles of triangle XYZ with respect to ∠X are ∠YXH and ∠ZXJ. Exterior angles of triangle XYZ with respect to ∠Y are ∠XYO and ∠ZYK . Exterior angles of triangle XYZ with respect to ∠Z are ∠XZN and ∠YZG. the sum of the exterior angle and the angle of triangle is 180° i.e. they make linear pair .२०१७ जुन २१
What is sector area formula?
The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.
How do you solve an inscribed angle?
By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc. The measure of the central angle ∠POR of the intercepted arc ⌢PR is 90°. Therefore, m∠PQR=12m∠POR =12(90°) =45°.

What is the sum of the measures of ∠ 1 and ∠ 2 What is the sum of the measures of 1 and 2 m1 m2?
By the definition of — angles, the sum of the measures of angles 1 and 2 is 180 degrees. Likewise, the sum of the measures of angles — is 180 degrees.
What is the degree measure of minor arc RS?
What is the degree measure of minor arc RS? The answer is 60 degrees, but I don’t understand how it’s not 30 degrees.
Why sum of exterior angle is 360?
Summed, the exterior angles equal 360 degreEs. A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.
What is the measure of Xbc?
How do you find the exterior angle?
To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides or angles that the polygon has. For example, an eight-sided regular polygon, an octagon, has exterior angles that are 45 degrees each, because 360/8 = 45.
What is an exterior angle in math?
1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.
What is the measure of ADB?
Answer: The measure of arc(ADB) is 270 degree. We know that the sum of all central angles of a circle is 360. Therefore the measure of arc(ADB) is 270 degree.
Do alternate exterior angles add up to 180?
When the two lines intersected by the transversal are parallel, corresponding angles are congruent, alternate interior angles are congruent, alternate exterior angles are congruent, and consecutive interior angles become supplementary, which means they have a sum of 180 degrees.२०२० फेब्रुअरी १७
What do you call an angle with a vertex on the circle?
An angle whose vertex lies on a circle and whose sides intercept the circle (the sides contain chords of the circle) is called an inscribed angle. The measure of an inscribed angle is half the measure of the arc it intercepts.
Which shows the order of the angles from smallest to largest?
Answer Expert Verified Since the smallest side is AC, this means the smallest angle is angle B. Since the middle length side is BC, the middle sized angle is A. Since the longest side is AB, the largest angle is C. This means the order from smallest to largest is B, A, C.
Do all exterior angles add up to 360?
the sum of all exterior angles equal 360, allexterior angles are the same, just like interior angles, and one exterior angle plus one interior angle combine to 180 degrees.
How do you find the degree of a minor arc?
The measure of a semicircle is 180°. The measure of a minor arc is equal to the measure of the central angle that intercepts the arc. We can also say that the measure of a minor arc is equal to the measure of the central angle that is subtended by the arc. In the diagram below, the measure of arc MN is 45°.
What is the measure of abd 51 degrees?
Question 489263: an angle measures 51 degrees, what is the measure of its supplementary angle? 180 – 51 = 129 degrees.
What is the measure of minor arc EG?
An arc defined by two rays is a fractional part of a circle. For example, the measure of an arc defined by a quarter of a circle is simply a quarter of 360 = 90 degrees. Points A, B, C, D lie in this order on the circumference of a circle. Minor arc AC is 160°, and minor arc BD is 140°.
What is the measure of angle COA?
Answer: The answer is C, 160.
What is the measure of angle ABD in trapezoid ABCD?
Answer Expert Verified 180- (24+116) = 40 degrees.
What is the measure of ∠ ABD?
The smaller angle (∠DBC) measures 30°. Since the ratio of angle measures is 2:1, the measure of the larger angle (∠ABD) has a value of 60° because 30 × 2 = 60.
What is the exterior angle of a triangle?
An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees.
