Question

Use a trigonometric ratio to solve for a. found to two decimal places as necessary cas22shapping to whoever gets it right

Answer 1

Answer: a = 16.62

Explanation:

sin(37) = 10/a

a = sin(37) / 10

a = 16.62

Answer 2

a ≈ 16.62

Explanation:

using the sine ratio in the right triangle

sin37° =
`(opposite)/(hypotenuse)` =
`(10)/(a)` ( multiply both sides by a )

a × sin37° = 10 ( divide both sides by sin37° )

a =
`(10)/(sin37)` ≈ 16.62 ( to 2 decimal places )
