Question

What is y? i am having trouble figuring out what y is

Answer 1

`\sf \boxed{\bf y =5√(22)}`

Explanation:

45° - 45° - 90° triangle:

The ratio of sides of 45 - 45 - 90 triangle is a : a : a√2.

a is the side opposite to 45°.

From the figure, a = 5√11

The side opposite to 90° is a√2.

y = a√2

`\sf = 5√(11) * √(2)\\\\ = 5*√(11*2)\\\\ = 5√(22)`
