pi x 6 x radius (ab or bc). Circumference is 2pir, 30 degree arc is 1/12 of circumference. In radian measure 30/57.3 ie 0.52 radians.
The sum of the two angles is 360. So angle ABC = 120 degrees.
Is angle C 90 degrees or 80 degrees?
It depends on what x is.
In a circle, the angle subtended by a diameter at the circumference is a right angle. Given that angle BAC is 50 degrees, and angle BAD is 105 degrees, we can find angle DBC by first finding angle ABC. Since angle ABC is the external angle to triangle ABD, it can be calculated as BAD - BAC = 105 - 50 = 55 degrees. Therefore, angle DBC, which is equal to angle ABC, is 55 degrees.
To find the measure of angle ABD, you can add the measures of angles ABC and CBD since they share a ray. Therefore, the measure of angle ABD is 40° + 23° = 63°. Thus, the measure of angle ABD is 63 degrees.
The sum of the two angles is 360. So angle ABC = 120 degrees.
67 degrees
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.
Anglw C is 63 degrees because the 3 interior angles of a triangle add up to 180 degrees
49 degrees
To have a congruent angle, the measure of the two angle must be the same, so if ABC is 15 degrees, then FDE would have to be 15 degrees also to be congruent.
83
the answer is 68 degrees
The angle is 50 degrees.
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
Is angle C 90 degrees or 80 degrees?
150 degrees
