Question

A right triangle has side lengths 5, 12, and 13 as shown below.

Use these lengths to find tanĄ, sin A, and cos A.

Answer 1

see explanation

Explanation:

tanA =
`(opposite)/(adjacent)` =
`(BC)/(AC)` =
`(5)/(12)`

sinA =
`(opposite)/(hypotenuse)` =
`(BC)/(AB)` =
`(5)/(13)`

cosA =
`(adjacent)/(hypotenuse)` =
`(AC)/(AB)` =
`(12)/(13)`
