Question

find x compute all outer and inner angles of the triangle first angle 80⁰ second x-20 third x​

Answer 1

Step-by-step explanation:

sum of all angles of triangle = 180°

80° + x -20 +x = 180°

2x + 60 ° = 180°

2x = 180°- 60°

2x = 120°

x = 60°

So, the second angle is 40°

And the third angle is 60°.
