Answer:
31
Step-by-step explanation:
Sum of interior angles of a triangle is 180,
x + 5 + x - 5 + 108 = 180
x + x + 5 - 5 + 108 = 180
2x + 0 = 180 - 108
2x = 72
x = 72 / 2
x = 36
B = x - 5
= 36 - 5
B = 31
Division by zero is not allowed in math because a that fraction is -5 parts out of 0 total parts
if you tried to divide by zero and tried to check by multiplying it out so for example
5/10=2
5=10 times 1/2
5/0=0
5=0 times (it is imposible because anything times 0 is 0)
so the answer is C
Answer:
106
Step-by-step explanation:
The area of one of the triangles is 1/2*5*3
The area is 7.5, but there are 2 triangles so the combined area is 15
The area for whole rectangle is 7*(5+3+5)=7*13=91
So the total area is 91+15= 106
