Sylvia leans a 4-foot broom against the wall. The angle between the bottom of the broom and the floor is 72°. How far up the wall does the broom reach from the floor rounded to the nearest tenth? 12.9 feet 3.8 feet 1.2 feet 0.2 foot
To solve this problem you must apply the proccedure shown below: 1.You have that the measure of the leans a 4-foot and the angle between the bottom of the broom and the floor is 72°. 2. Then, you have:
Sin(72°)=x/4
When you solve for x, you obtain the following result:
