Find the exact value of z.

a² + b² = c²

First find out the length of the line in the middle. We know that a² + 16² = 27², which means a = √473

Now write out all the equations for all the right triangles in the diagram.

Let the side of the base of the triangle be x and the remaining sides of z be y.

x² + 27² = (16+ y)²

y² + (√473)² = x²

From here solve and find y. Once you get y, y + 16 is your z, the answer.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
