Answer:
P = 12x +32
Step-by-step explanation:
The perimeter is found by using the formula
P =2(l+w)
We know the length and the width
P = 2(x+4 + 5x+12)
Combine like terms
P = 2(6x+16)
Distribute
P = 12x +32
The answer would be 65°.
This is because 180° -50° equals 130°. And 130° divided by two equals 65°. The two remaining angles must be equal because it is an isosceles triangle.
