Step-by-step explanation:
![-8x=-90\qquad\text{divide both sides by (-8)}\\\\\dfrac{-8x}{-8}=\dfrac{-90}{-8}\\\\x=\dfrac{90}{8}\\\\x=\dfrac{90:2}{8:2}\\\\x=\dfrac{45}{4}\to x=11\dfrac{1}{4}](https://tex.z-dn.net/?f=-8x%3D-90%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%20%28-8%29%7D%5C%5C%5C%5C%5Cdfrac%7B-8x%7D%7B-8%7D%3D%5Cdfrac%7B-90%7D%7B-8%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B90%7D%7B8%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B90%3A2%7D%7B8%3A2%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B45%7D%7B4%7D%5Cto%20x%3D11%5Cdfrac%7B1%7D%7B4%7D)

Answer:
C
Step-by-step explanation:
The 3 is directly outside the parentheses, meaning you need to distribute the 3 to the x and the 4 because they are inside the parentheses. There is no addition, subtraction, or division involved in this so C is correct.
Answer: x=6 and the angle is 50
Step-by-step explanation:

3. subtract 2 from 50 and get 48
4. divide 48 by 8 and you get 6.
