Okay, to do this, we need to do the Cross-Product Method. On one side, it will be x/90, and the other side will be 15/100. So, after we multiply 90 by 15, and also multiply 100 by x, out new equation is going to be 100x = 1350. After dividing 1350 by 100, we get 13.5
Answer: 15% of 90 hours is 13.5 hours.

Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:
We can solve for x shown below:
The value of x is -2
