Answer:
option b 5√2
option a 20
option c 4
option d 3/4
option b 3
Step-by-step explanation:
To solve all these questions we will use trigonometry identity which says that
sinΔ = opposite / hypotenuse
1)
sin45 = 5 / KL
Kl = [tex]\frac{5}{\frac{\sqrt{2}}{2} }[/tex]
KL = 5√2
2)
TanФ = opp / adj
Ф = Tan^-1(5/14)
Ф = 19.65
≈ 20
3)
sin(30) = rq / 8
rq = sin(30)(8)
rq = 4
4)
tan(Ф) = 6/8
5)
angle 3
