Since the lines a and b are parallel, <4 and <8 are of the same measure. To find <8, we can simply subtract the measure of <7 from 180 degrees.

<4 = <8 = 180 - <7 = 180- 114 = 66 degrees

HELP ASAP!!!!!!!!!!!!!! WILL MARK BRAINLIEST PICTURES BELOW!!!!!!!!!!!!!!!!!!!!!!!!!
harkovskaia [24]

5. 6√3

6.  x = 10√3     y = 30

7. x = 34    y = 17√3

8. 30

9. SinA = 3/5       CosA = 4/5

10. Tan20 = 9/x

Multiply both sides by x to get it on the other side

x(tan20) = 9

Divide 9 by tan20 to get x.

x = 9/tan20

x = 24.7

What number should both sides of the following equation be multiplied by to solve for g? g divided by 2 = 4
77julia77 [94]

Answer: Multiply both sides by 2.

Step-by-step explanation:

g divided by 2  is equal to 4 .

We could represent that with the equation :

\frac{g}{2} = 4     To solve for g  in this case multiply both sides by 2.

\frac{g}{2} * 2 = 4(2)     2 cancels out on the left side so we will be left with g. On the right side will be left with 8  after multiplying.

g = 8
