m∠k=(6x + 12)°. find the measure of the complement of ∠k.
(67 - 6x)°
(78 - 6x)°
(102 + 6x)°
(112 + 6x)°

Explanation:

Step1: Complement definition

Complement = 90° - angle

Step2: Substitute angle K

Complement = 90 - (6x + 12)

Step3: Simplify expression

= 90 - 6x - 12 = 78 - 6x

Answer:

B. (78 - 6x)°
