Question

An angle measures 70° less than the measure of its complementary angle. What is the measure of each angle?

Answer 1

let's let one angle be x

"an angle measures 70 less than the measure of its complementary angle" so if we let the complementary angle be x, the other angle is x - 70

if two angles are complementary, then they add up to 90 degrees

therefore, x + (x-70) = 90

solve for x. that's the measure of one of the angles.

from there, also calculate x - 70 to get the other angle.
