An angle measures 42.6° less than the measure of its complementary angle. What is the measure of each angle?
Setler79 [48]

Answer:

Complementary angle 1st = 66.3°

Complementary angle 2nd = 23.7°

Step-by-step explanation:

Assume;

Complementary angle 1st = a

Complementary angle 2nd = a - 42.6°

Sum of complementary angles = 90°

So,

a + a - 42.6 = 90

a = 66.3

Complementary angle 1st = 66.3°

Complementary angle 2nd = 23.7°

If f(x)=25-2x, then f(5)=<br> Some please help
gizmo_the_mogwai [7]
F(x) = 25 - 2x

f(5) is pretty much the value of f(x) when x = 5

Plug x=5 into f(x)

f(5) = 25 - 2(5)
= 15

That's your answer.

Have an awesome day! :)
