The measure of the exterior angle is the sum of the two remote interior angles. So add ur 2 remote interior angles, and that will be the measure of the exterior angle
Answer:
the answer would be 47.75981574 or 47.76
Answer:
D. 63°
Step-by-step explanation:
a = 27°
b = 180° - (a + 27°)
b = 180° - (27° + 27°)
b = 180° - 54°
b = 126°
By inscribed angle theorem:
c = 1/2 b = 1/2 * 126°
c = 63°
(4x-13)°+15°+(x+18)°=180
4x-13+15+x+18=180
5x+20=180
5x=180-20
x=32
A=(4x-13)°
=(4×32-13)°
=115°
C=x+18°
=32+18°
=50°
HOPE IT HELPS UH!!☺️☺️
