Q120 of 158 Page 159

In a right-angled triangle if an angle measures 35°, then find the measure of the third angle.

Given: In right angle triangle one angle is 35°


Formula Used/Theory:-


Angle sum property


Sum of all angles of triangle is 180°


In a right angled triangle


One angle is always 90°


Another given is 35°


Let the 3rd angle be X


Hence;


By angle sum property


90° + 35° + X = 180°


X = 180° - 125°


= 55°


Result:- The 3rd angle comes out to be 55°
