Question

Need help ASAP!! (Geometry) *Attachments*

Answer 1

option b 5√2

option a 20

option c 4

option d 3/4

option b 3

Explanation:

To solve all these questions we will use trigonometry identity which says that

sinΔ = opposite / hypotenuse

1)

sin45 = 5 / KL

Kl =
`(5)/((√(2))/(2) )`

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
