Angle a​ and​ ​angle b​ ​are complementary angles. The measure of ∠a is 42°. Which equation represents this situation with x representing the measure of ∠b ?

Respuesta :

We know, sum of complementary angles are 90 degrees
So, a + b = 90     [ Equation ]

For solving: Just substitute the value of a = 42
42 + b = 90
b = 90 - 42
b = 48

Hope this helps!
