Step-by-step explanation:
Hello James!
Graph using the slope and y - intercept.
Slope:

Y-intercept: -3
The graph looks like this ↓↓↓
I think that the answer would be B
39° or B that should be it
For this case we can make use of the Pythagorean theorem.
We have then:
(root (117)) ^ 2 = x ^ 2 + 6 ^ 2
Clearing x we have:
x ^ 2 = (root (117)) ^ 2 - 6 ^ 2
Rewriting:
x = root (117-36)
x = root (81)
x = 9
Answer:
The value of x is given by:
x = 9 cm
