Answer:
The value of an exterior angle is the sum of the two interior angles not adjacent to it so
a:
x = 64 + 45 = 
b:
3x + 6 = 153 so
3x = 147 so
x = 

Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in

Answer:
C. x = 11, m∠Q = 55º
Step-by-step explanation:
125 + 5x = 180
5x = 55
x = 11
5x = 55
C. x = 11, m∠Q = 55º

Answer:
92.5
Step-by-step explanation:

cross multiply:
18.5 · 500 = 9250
100 · x = 100x
isolate x by dividing 100 from both sides:
x = 92.5
hope this helps!
