Question

find the value of x. Round to the nearest degree

Answer 1

x = 51 degrees

Explanation:

(to find x, use sine)

Sine =
`(opposite)/(hypothenuse)`

⇒ Sine x =
`(7)/(9)`

⇒
`(7)/(9)` = 0.78

⇒ Sine x = 0.78

then calculate what Sine-1 of 0.78 is:

⇒ Sine-1 of 0.78 = 51.26

x = 51.26

Round to the nearest degree:

51.26 ⇒ 51 degrees

Answer 2

51 degress

Explanation:

sin x = 7/9

x = sin^-1 (7/9)

simply using a calculator.
