Question

if angle a is vertically opposite to angle b and and a is 72degrees then find the measure of the angles a,b,c,d​

Answer 1

Step-by-step explanation:

A=72°(VOA)

angle B=D(VOA)

B=x

so,D=x

x+x+72°+72°=360°(ANGLE AT A POINT)

2x+144°=360°

2X=360°-144°

2x=216°

x=216°÷2

x=108°

A=72°

B=108°

C=72°

D=108°
