Question

9. Find the missing lengths of the sides.

Answer 1

Answer:

x = 8

y = 8$\sqrt{2}$

Step-by-step explanation:

This is a special right triangle with angle measures 45-45-90

The side lengths for this triangle are as follows

a (the side lengths that see angle measure 45)

a$\sqrt{2}$ (the side length that sees angle measure 90)

one of the side length which sees angle measure 45 is given as 8

so a = 8 as well as x = 8

therefore y = 8$\sqrt{2}$
