Answer:
The Value of Y is 25.
The Value of Z is 144.
Explanation:
Find Value of Y using Phytagorean Theorem

Substitute
 
 
Simplify
3,600 + 
 = 4,225
 = 4,225
Transpose 3,600 to the other side, since 3,600 is a positive number, it will become negative.
 = 4,225 - 3,600
 = 4,225 - 3,600
Subtract

Find the Square root of both sides
b = 25
Find the Value of Z Using Phytagorean Theorem

Substitute 

Simplify
3,600 + 
 = 24,336
 = 24,336
Transpose 3,600 to the other side, since 3,600 is a positive number, it will become negative.
 = 24,336 - 3,600
 = 24,336 - 3,600
Subtract
 = 20,736
 = 20,736
Find the Square root of both sides
b = 144
Hope this helps!
