Question

Greatfull in advance :)

Answer 1

160 m

Explanation:

For the 15-deg angle, h is the opposite leg.

The hypotenuse is 628 m.

The trigonometry ratio that relates the opposite leg and the hypotenuse is the sine.

sin A = opp/hyp

`\sin 15^\circ = (h)/(628~m)`

`h = 628~m * \sin 15^\circ`

`h = 162.54~m`

Rounded to 2 significant figures:

h = 160 m
