The measures of two angles in a triangle are 48° and 71°. What is the measure of the third angle?

The sum of the 3 angles needs to be 180.

To find the third angle subtract to the known angles from 180.

180 - 48 - 71 = 61

The third angle is 61 degrees.

its a

step-by-step explanation:

true

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
