Answer:
x is a number that is multiple by 3
Step-by-step explanation:
00000009999000000p00
Quadratic equation is

WHEN

So, to make this true subtract 7 from each side.
The equation is now
7

- x - 7 = 0
Values for a, b, and c: a = 7, b = -1, c = -7
Plug these variables into the quadratic equation.
Square -1 to get 1 and multiply -4 x 7 x -7 to get 196.

Multiply 2 x -7 to get -14, the denominator, and add 1 to 196.
Since 197 is not a square number, and I don't know if you want to leave it in radical form or not, I will just because it's easier to understand.
Hope this helps!
Answer:
x = 21 degrees
Step-by-step explanation:
Vertical angles are always congruent.
3x + 67 = 130
3x = 130 - 67
3x = 63
<u>x = 21</u>
