Find the value of x and y
I don’t know how

x = 2√30, y = 2√21

Step-by-step explanation:

You can create the following equations:

(1) from the left triangle with sides x, y and 6:

y² + 6² = x²

(2) from the right triangle with sides y, 14 and... lets call it z:

y² + 14² = z²

(3) from the big triangle:

x² + z² = 20²

(4) Combine (2) and (3) to eliminate z:

x² + y² + 14² = 20²

combine (1) and (4) to eliminate x:

y² + 6² + y² + 14² = 20²

simplify

2y² = 20² - 6² - 14² = 168

y² = 84

y = √84 = 2√21

x² = y² + 6² = 84 + 36 = 120

x = √120 = 2√30

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
