Question

What are the values of x and y?

Answer 1

Answer:

Step-by-step explanation:

y is the value obtained from 4 and 12

y^2  =  4 * 12            Combine

y^2 = 48                   Square root both sides.

√y^2 = √48

y = √(3 * 4 * 4)

y = 4√3

Use the Pythagorean Theorem to obtain x

x^2 = y^2 + 4^2

x^2 = 48 + 16

x^2 = 64                    Take the square root of both sides

√x^2 = √64

x = 8

Answer

• x = 8
• y = 4√3
