What are the values of x and y?
1 answer:
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:
4 sqrt(3) cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
48 = s^2
Take the square root of each side
sqrt(48) = sqrt(s)
sqrt(16*3) = s
4 sqrt(3) =s
