Answer:
1st angle: 80°
2nd angle: 10°
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.
