Answer:
99
Step-by-step explanation:
You subtract 45 and 36 from 180
13×36
the angle wants you to multiply 13×36
m=6
8(3+7m)=360
24 + 56m = 360
-24 -24
56m = 336
/56 /56
m = 6
C) 6 ft
Perimeter is just adding the side lengths together so...
31-15-10=x
6=x
so your answer is 6ft
Try this solution, it consists of two parts (MN=8).
