Question

Find all 3 interior angles abc and in this form (BCA+DCB) ​

Answer 1

Answer:

A = 65°

B = 50°

C = 65°

BCA+DCB = 130° + 65°

= 195°

Step-by-step explanation:

For Angle B

180°-130°=50°

For Angle A & C

A + B + C = 180°

x + 50° + x = 180°

2x = 130°

x = 65°

Hence A & C both are 65°
