Answer:

1st angle: 80°

2nd angle: 10°

Step-by-step explanation:

Complementary angles add up to 90 degrees. Make the first angle be represented by 4x + 40, and the second angle be represented by x.

Make both expressions add up to 90.

(4x + 40) + (x) = 90

Combine like terms.

5x + 40 = 90

Subtract 40 from both sides.

5x = 50

Divide both sides by 5.

x = 10

Now substitute 10 for x into the expression representing the first angle.

4(10) + 40 = 80

Now we know that the first angle is 80 degrees and the second angle is 10 degrees.
