Question

Please help me solve :(((

Answer 1

θ ≈ 15°

Explanation:

Using the sine rule in the triangle

note 7.56 × 10² = 756 and 2.4 × 10³ = 2400 , then

`(756)/(sin0)` =
`(2400)/(sin125)` ( cross- multiply )

2400 × sinθ = 756 × sin125° ( divide both sides by 2400 )

sinθ =
`(756sin125)/(2400)` , then

θ =
`sin^(-1)` (
`(756sin125)/(2400)` ) ≈ 15° ( to the nearest degree )
