Question

Find the value of x. please. If your answer is not an integer, write it in simplest radical form with the denominator rationalized.​

Answer 1

x =
`(13)/(2)`

Explanation:

Using the sine ratio in the right triangle and the exact value

sin30° =
`(1)/(2)` , then

sin30° =
`(opposite)/(hypotenuse)` =
`(x)/(13)` =
`(1)/(2)` ( cross- multiply )

2x = 13 ( divide both sides by 2 )

x =
`(13)/(2)`
