Question

Good evening, I need help on question 3. For a geometry practice question. Please help:) I believe it’s using the SOA. CAH TOA method

Answer 1

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).
