angles are complementary. One angle has a measure of 40° and the other has a measure of (8x + 2) °. What is the value of x? (1 point)
• 6
• 11
• 60
• 50
To determine the value of x, we need to use the fact that complementary angles add up to 90 degrees.
So, we can write the equation:
40 + (8x + 2) = 90
To solve for x, begin by simplifying the equation:
8x + 42 = 90
Subtract 42 from both sides:
8x = 48
Divide both sides by 8:
x = 6
Therefore, the value of x is 6.
The correct answer is: 6.
