If the measure of two angles of a triangle are 35°, 84°, then the third angle is ……………..? A) 51°B) 61°C) 69°D) 59°

Answer»

Correct option is B) 61°

Given two angles are 35° and 84°.

Let the third angle be x°

\(\because\) sum of angles in a triangle is 180°

\(\therefore\) 35 + 84 + x = 180

⇒ x = 180 - (35 + 84)

= 180 - 119

= 61

\(\therefore\) Third angle is 61°.
