which equation can be used to find x, the length of the hypotenuse of the right triangle?

16 + 63 = x

16^2 + 63 = x

(16 + 63)^2 = x^2

16^2 + 63^2 = x^2

D.) 16^2 + 63^2 = x^2

Step-by-step explanation:

The Pythagorean Theorem supports my answer. When given a right angled triangle, the equation a^2+b^2=c^2 should be used to find the missing variable/angle. In this case, when substituting the numbers in the variables, you are left with the correct answer D.

I hope this helped!!

step-by-step explanation:

it is the one with the most keychains.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
