Answer:
P=50
Step-by-step explanation:
First use the formula for perimeter which is P = 2l + 2w. Then plug in to find your answer.
STEPS:
P = 2l + 2w
P=2(13)+2(12)
P=26+24
P=50

Answer:
k = 10
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ZYM is an exterior angle of the triangle, thus
4k + 5 + 6k + 10 = 115, that is
10k + 15 = 115 ( subtract 15 from both sides )
10k = 100 ( divide both sides by 10 )
k = 10
