Question

Two angles are complementary. They have measures of (7x + 2)° and (3x – 2)°, respectively. What is the value of x?

Answer 1

Complimentary angles add up to 90 degrees.
That tells us that our two angles will add up to 90 degrees.\[\Large\bf\sf (7x+2)^o+(3x-2)^o\quad=\quad 90^o\]

Answer 2

Do you understand how to solve for x from this point?

Answer 3

yes thank you
