Question

Simple geometry please help

Find KL. Round to the nearest hundredth.

Answer 1

KL ≈ 1.94

Explanation:

Using the cosine ratio in the right triangle

cos48° =
`(adjacent)/(hypotenuse)` =
`(JL)/(KL)` =
`(1.3)/(KL)` ( multiply both sides by KL )

KL × cos48° = 1.3 ( divide both sides by cos48° )

KL =
`(1.3)/(cos48)` ≈ 1.94 ( to the nearest hundredth )
