Find the value of z.

can someone help me please?

Answer 1

Answer 2

To find the value of Z yo must first find the value of Y

Answer 3

Use the pythagorean theorem to find Y and use the pythagorean theorem again to find Z

Answer 4

since you have 2 90 degree angles

Answer 5

Pythagorean Theorem\[A^2+B^2=C^2\] Where C is the hypotenuse

Answer 6

Plugging in what you know
A= y
B= 1
C = 3

Answer 7

Using that same method and seeing that Z is the hypotenuse you can find Z

Answer 8

For the Second triangle on the right,
A = Y
B = 8
C = Z

So you can see that you first need the value of Y
