Don’t know how to solve, help ?

I believe the answer is 88 because the 120 will create a straight angle which is 180. Then you do 180-120=60. This is the measure I the left angle. Now your answer will be 88

Use the intersect method to solve: x^2+1=-x^2+9
Sergio [31]

Answer:

x={-2,2}

Step-by-step explanation:

Graph them when intersecting.

Algebraically:

x^2 + 1 = -x^2 + 9

Add x^2 on both sides and subtract 1 on both sides.

2x^2 = 8

Divide 2 on both sides

x^2 = 4

Square root on both sides

|x| = 2

Remove abs value by putting + or - on the other side

x = {-2,2}
