Question

Given that r = 9.2 m and = 17", work out AB rounded to 3 SF
​

Answer 1

It would have to be 2.81m

Answer 2

2.813 m

Explanation:

x = 9.2 θ = 17 AB=?

Looking at our angle we have an adjacent side & need to find the opposite side.

So tan θ = opp/adj

tan 17 = AB/9.2

AB = 9.2tan17

AB = 2.813 m
