Answer: 8.4
Explanation: Substitute y = 0.8 into the equation.
4x + 8(0.8) = 40
4x + 6.4 = 40
4x = 33.6
x = 8.4

Answer:
69.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees so we have the equation:
4x + 3 + x + 4 = 90
5x + 7 = 90
5x = 83
x = 16.6
The larger angle = 4x + 3
= 4(16.6) + 3
= 69.4 degrees (answer).
The answer to the first question is complementary angles.
The measure of angle WOV is 60
the answer to the third question is vertical angles.
The measure of YOZ is 60 because vertical angles are equal to each other and YOZ is vertical to WOV
