ANSWER:

As we know , the sum of the angles of a triangle is equals to 180 degrees, simply we need to subtract the sum of given angle from the sum of all angles, which is 180. so, we get:

⇒ 180° - 90° + 30°

⇒ 180° - 120°

⇒ 60°

Hence, the answer is 60°.

Answer 2

Given : Two angles of a triangle measure 90° and 30°

To Find :  The measure of the third angle is

Solution:

Triangle angle sum property :

Sum of measures of  all three angles of a triangle is 180°

Measures  of Two angles are given as 90° and 30°

Assume that measure of third angle is  x

x + 90° + 30°  = 180°

=> x + 120° = 180°

=>  x= 180° - 120°

=> x = 60°

Hence measure of third angle is  60°
