Trig q (1 Viewer)

Can anybody help me with this q, probably pretty easy but I’m not very good at trig and catching up on what I’ve missed.

To solve this question, you first need to identify w. To do so, you do:

tan(39) = w/15.19
tan(39) x 15.19 = w
w=12.87m (2.dp)

After this, you solve for theta like so:

tan(θ) = 12.87/8.5 --> i got 8.5 from substracting 7.4 from 15.9
θ= tan^-1(12.87/8.5)
θ=56°33' and thats ur answer!
