Question
A hawk sitting on a tree branch spots a mouse on the ground 15 feet from the base of the tree. The hawk swoops down toward the mouse at an angle of 30 degrees. Calculate the distance from the tree branch to the mouse.
- 7.5 ft.
- 15 ft.
- 26 ft.
- 30 ft.
Hint:
Sin x = opposite side/Hypothenuse side
The correct answer is: 30 ft.
BC=15m
sinA=AC/BC
sin30=AC/15
⟹2/1=AC/15
⟹AC=30ft
