Question

find value of a, b, c​

Answer 1

Step-by-step explanation:

45° + B = 65 ............exterior angle thm

B = 65° - 45°

B = 20 °

A + B = 65° ........... alternet angle

A + 20° = 65°

A = 65 - 20

A = 45°

A + B + C = 180° .........angles in linear pair

45 + 20 + C = 180

C = 180 - 65

C = 115 °
