Two complementary angles have measures (4x)° and (2x)°. What is the value of x and the two angle measures?

x= 15 , (4x)°=, and (2x)°, = °

Plugging in x = 15 into the expressions for the angle measures, we have:

(4x)° = 4(15)° = 60°
(2x)° = 2(15)° = 30°

Therefore, x = 15, (4x)° = 60°, and (2x)° = 30°.
