Question

Two angles of a traingle are of measure 60 and 75 find the third angle​

Answer 1

$let \: third \: angle \: be \: x \\ \\ x + 60 + 75 = 180 \\ x + 135 = 180 \\ x = 180 - 135 \\ x = 45$

Answer 2

●As we know that the sum of all angles in a triangle is 180°.

=>so, Let third angle be x.

=>60°+75°+x = 180°

=>x=180-135

=>x= 45°.
