Question

Find the measure of a, b, c in the given figure

​

Answer 1

Answer:

a=60,

b=23 do sum of triangle

,c=157 this straight line 180

Answer 2

Answer:

a=115°

b=85°

c=23°

Step-by-step explanation:

1) a=

180°-125°=115°....(angles on straight line)

2)c=

180-78=102°

180-(102+55)

=180-157

=23°

3)b=85 degree

by solving triangle ABCD

c=72°

then,180-95°=85°
