The two angles are vertical angles, which means they are the same.
Set the two equations to equal and solve:
2x +2 = 3x -52
Subtract 2x from each side:
2 = x -52
Add 52 to each side:
x = 54
Answer:
b. a = negative 1, b = 5, c = 0
Step-by-step explanation:
y = negative x squared + 5 x
y = -x² + 5x
a = -1
b = 5
c = 0
Make sure D is by its self so
90=6(d-84)
Divide both sides by 6 to get rid of 6 from the right side so
90/6= (d-84)
15 =(d-84)
Now get rid of the 84 by adding it
15+84= d
99=d therefore d is equal to 99
