Answer:
D
Step-by-step explanation:

=
Factor out 2 on the numerator and 2x on the denominator.
= 
Cancel the factor (x + 2) on the numerator/ denominator
=
← cancel the 2 on numerator/ denominator
=
: x ≠ 0
Angles PMN and MPN are also 16 because the triangles are isosceles.
The measure of the third angle (angle N) is 148 which also equal to the measure of angle K. The measure of angle PKE is 74 which half of the measure of angle N and angle K.<span />
I would say to check the 1st and 3rd
Answer:
12 is the answer. cause 5×12 is 60 and the missing angle is 60 degrees
