Question

in a triangle abc angle a =80° ,angle b=20° find the value of angle c​

Answer 1

$\sf{\huge{\underline{\green{Given :-}}}}$

• The two angles of a triangle are 80° & 20°.

$\sf{\huge{\underline{\green{To\:Find :-}}}}$

• The third angle of a triangle.

$\sf{\huge{\underline{\green{Answer :-}}}}$

According to the question,

In a triangle ABC angle,

• ∠a = 80°

• ∠ b = 20°

We know that, the sum of all angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

➝ 80 + 20 + ∠C = 180°

➝ 100 + ∠C = 180°

➝ ∠C = 180° - 100°

➝ ∠C = 80°

The third angle of a triangle is 80°.

Answer 2

Answer:

Value of C=80°

A=80° B=20° C=80°
