Question

Plzz helppp it's due today​

Answer 1

Explanation:

sin 30° =
`(4)/(x)`

x =
`(4)/(sin 30)`

x =
`(4)/(0.5)`

x = 8

Answer 2

8

Explanation:

use trig functions

2 sides and 1 angle given

Sides given

• hypotenuse -> x
• opposite side to 30˚ -> 4

Angle

• 30˚

trig function associated with hyp and opp is sin

sin(x) = opp/hyp

substitute

sin 30˚ = 4/x

solve for x

0.5 = 4/x

0.5x = 4

x = 8
