could you use the tangent, ill be honest im totally new to trig

Answer 3

yup that's right.
so what's tan 39 equal to?

Answer 4

aw @mustafa2014 you're such a spoiler. :(

Answer 5

srry :)

Answer 6

@cwright150 , what do you think we'll do next?

Answer 7

Answer 8

let's solve for z!
tan36 = z/4
hence z = 4tan36

Answer 9

ok

Answer 10

how would i solve that further

Answer 11

it'll be better if you master/memorise trig functions.
after that, algebra follows

Answer 12
