Question

Find the measure of the third angle of a triangle if the measures of the other two angles are given. 29.7° and 83.5°

Answer 1

Here,
1st angle = 29.7
2nd angle = 83.5
let the third angle be x.
Then,
sum of angle of a triangle = 180
or, 29.7 + 83.5 + x = 180
or, x = 180 - 113.2
or, x = 66.8

answer= 66.8
