Question

Angles of measure ( a+5) and and (40-15) are complementary. What is the measure of each angle

Answer 1

Answer:1st angle=(a+5)°
2nd angle=(40-15)°
Since they are supplementary,
Therefore,
a+5+40-15=90°
a+45-15=90°
a+30 =90°
a =90°-30
a=60°
Therefore,1st angle=(a+5)=60°+5=65°
And, 2nd angle=(40-15)° =25°
