Use Pythagorean Theorem to solve for x.

HELP ME PLZ ASAP

Step-by-step explanation:

Pythagorean theorem: , where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

Since we don't know what  is, we're going to isolate it by subtracting 81 on both sides

We have to square root both sides in order to find out b (or x in the problem).

When you put this on a calculator it would result in which is the answer d in the problem.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
