Question

Find the distance to the oil platform from each end of the beach. Enter both values.

Answer 1

3671.8, 3576.4

Explanation:

The third angle of the triangle is 19°.

Let the first length be a. Then,

`(a)/(\sin 85^(\circ))=(1200)/(\sin 19^(\circ)) \\ \\ a=(1200\sin 85^(\circ))/(\sin 19^(\circ)) \approx 3671.8`

Let the second length be b.

`(b)/(\sin 76^(\circ))=(1200)/(\sin 19^(\circ)) \\ \\ b=(1200\sin 76^(\circ))/(\sin 19^(\circ)) \approx 3576.4`
