Question

Trigonometry, find the missing side(s)​

Answer 1

x = 8.92 units

Explanation:

From the triangle given in the picture,

Missing side of the triangle is the opposite side of the angle measuring 28°

And hypotenuse measuring 19 units has been given.

So, we will use sine ratio for the given angle.

sin(28°) =
`\frac{\text{Opposite side}}{\text{Hypotenuse}}`

sin(28°) =
`(x)/(19)`

x = 19sin(28°)

x = 8.92 units
