Since the two angles are complementary, their measures add up to 90°. Therefore, we can set up the equation:
40° + (8x + 2)° = 90°
Adding like terms:
8x + 42 = 90
Subtracting 42 from both sides:
8x = 48
Dividing both sides by 8:
x = 6
The value of x is 6.
The correct answer is D. 6.
40° + (8x + 2)° = 90°
Adding like terms:
8x + 42 = 90
Subtracting 42 from both sides:
8x = 48
Dividing both sides by 8:
x = 6
The value of x is 6.
The correct answer is D. 6.
