Minus 180 from 190. You have -10
2x= -10
Which means x equals -5

That's correct. Now you gotta plug in -5 in for x and get both angles.

Point h is between g and i. If gh = 2x2 + 7x, hi = 9x – 2, and gi = 38, find the length of gh, hi and the possible values of x.

yuradex [85]

2x²+7x+9x-2=38
2x²+16x-40=0
2(x²+8x-20)=0
2(x+10)(x-2)=0
x=-10 or x=2
if we let x=-10 we get negative lengths for some of the segments which is not allowed so discard it. for x=2,

gh=22, hi=16, and gi=38

What is the equation of a vertical line passing through (-5, -2)?

elena-s [515]

Answer:

x=-5

Step-by-step explanation:

if point the line is passing through is -5, -2 and the line is vertical than x would have to stay the same no matter where the y is because it's vertical.
