Question

The interior angles of a triangle measure 110° and 25°. What is the measure of the third
angle

Answer 1

Answer:

The measure of third angle angle is 45

Step-by-step explanation:

Let the unknown angle be x,

We know that, sum of all angles of a triangle = 180

110 + 25 + x = 180 {by angle sum property}

138 + x = 180

x = 180 -135

x = 45

hence the unknown angle is 45
