Two angles of a triangle are 65∘ and 45∘ then the third

| Two angles of a triangle are

65^{\circ}

and

45^{\circ}

then the third angle is:

A. $60^{\circ}$

B. $80^{\circ}$

C. $70^{\circ}$

D. $75^{\circ}$

Please scroll down to see the correct answer and solution guide.

Right Answer is: C

SOLUTION

Let the third angle be 'x'
From angle sum property of a triangle, we have
$65^{\circ} + 45^{\circ} + x^{\circ} = 180^{\circ} \Rightarrow x = 180^{\circ} - 110^{\circ} \Rightarrow x = 70^{\circ}$
