Answer:
x=3.5
step-by-step explanation:
to understand the solving steps
you need to know about:
- trigonometry i.g cos=ad/hypo
- equation
- PEMDAS
given:
hypo:6.5
angle:57°
to solve:
x
let's solve:
according to the question
[tex] \cos( {57}^{o} ) = \frac{x}{6.5} [/tex]
[tex]x = 6.5\cos( {57}^{o} ) [/tex]
[tex]x = 3.5[/tex]
