Question

what is the measure of the third angle of a triangle if the first angle measure is 22° and the second measure is 35°​

Answer 1

123°

Explanation:

the sum of the 3 angles in a triangle = 180° , then

third angle + 22° + 35° = 180°

third angle + 57° = 180° ( subtract 57° from both sides )

third angle = 123°
