What is X if Y is 12.8 and Z is 16 in the right triangle below?

Im 90% sure its H.

Step-by-step explanation:

H) 9.6

Step-by-step explanation:

Use the pythagorean theorem to solve for a right triangle.

Pythagorean Theorem: a^2 + b^2 = c^2

So, 16^2= 12.8^2 + x > 256= 163.84 + x^2 (subtract 163.84 from both sides of the equation) > x^2= 92.16 (square root) > x=9.6

This is my first answer so I hoped it helped! :)

step-by-step explanation:

first, eliminate the parenthesis:

3

x

+

2

−

4

x

second, group like terms:

3

x

−

4

x

+

2

third, combine like terms:

(

3
