One angle measures 18°, and another angle measures (6d − 6)°. If the angles are complementary, what is the value of d?
d = 2
d = 13
d = 31
d = 36.2
To find the value of d, we need to set up an equation using the information given.
Since the angles are complementary, their sum must be 90 degrees.
18 + (6d - 6) = 90
Simplifying the equation:
6d + 12 = 90
Subtracting 12 from both sides:
6d = 78
Dividing both sides by 6:
d = 13
Therefore, the value of d is 13.
