Question

Using trig to solve for the missing angle

Answer 1

Explanation:

Since there is a 45 and 90 degree angle, this is a 45-45-90 triangle. The legs are equal in a 45-45-90 ttiangle. The hypotenuse sqr root of 2 times more than the legs. So this means the hypotenuse measure is

`18 √(2)`

So we can set up a equation.

`{18}^(2) + {x}^(2) = ({18 √(2)) }^(2)`

`x = 18`

So the missing side is 18
