Number 3.
From the diagram an the positioning of the angle and the sides, we will be using TOA, because we were given opposite and adjacent.
recall that:
Tan θ = Opposite Using SOHCAHTOA.
Adjacent
We were given:
θ = 48˚
Adjacent = 17
Opposite = x
So, lets input into the above formular:
Tan 48˚ = x
17
Let's cross multiply
x = Tan 48˚ (17)
x = 1.1106 * 17
x = 18.8804
x = 18.88 ( to the nearest tenth).
