Question

Find the missing lengths in right triangle mno. Estimate your answer your answer to two decimal places..

Answer 1

x = 11.79

? = 6.25

Explanation:

Using the law of sines

`(10)/(sin58)` =
`(x)/(sin90)`

x = sin 90° x
`(10)/(sin58)` = 11.79

by Pythagorean theorem,

?² + 10² = x²

? = √ (x²- 10²)

? = √ (11.79²- 10²) = 6.25
