Answer:
what
Step-by-step explanation:
2) vertical angles
vertical angles are always across from each other where two lines cross

angle 1 and angle 3 are also vertical
angle 4 and angle 2 are also vertical
hope this helps :)

B. -7≤X≤7
So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8
so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6
Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2
