Find the measure of the third angle of a triangle if the measures of the other two angles are given. 118.6 and 42.3 a)39.1 b) 36.7 c) 19.1 d) 29.1 no guessing and show work you.

The measure of the third angle of a triangle is 29.1.

Given that,

The measures of the other two angles are given. 118.6 and 42.3

We have to determine,

The measure of the third angle of a triangle.

According to the question,

The measure of the third angle is determined by using the properties of the triangle following all the steps given below.

The sum of three angles in a triangle is equal to 180 degrees.

The measures of the other two angles are given. 118.6 and 42.3.

Therefore,

The measure of the third angle of a triangle is,

Hence, The measure of the third angle of a triangle is 29.1.

recall from the previous posting, the sum of all interior angles in a triangle is 180°.

so the third one will be 180° - 118.6° - 42.3°.

the answer is d
