Question

If one angle of a triangle is 80° what are the two other angles​

Answer 1

$\boxed{\textbf{Answer}}$

Let two angles be x

We know,

Sum of three angles of a triangle is 180°

80 + x+ x = 180°

=> 80 + 2x = 180°

=> 2x = 180° - 80°

=> 2x = 100°

=> x = 100° ÷ 2

Therefore, x = 50°

$\boxed{\textbf{Verification}}$

50° + 50° + 80° = 180°

100° + 80° = 180°

180° = 180°

Hence proved.
