To solve this problem you must apply the proccedure shown below:
1. You have that:
- The10-foot ladder is leaned against a wall.
- The angle between the base of the ladder and the ground measures 62°.
2. Therefore, you have:
Sinα=opposite/hypotenuse
α=62°
opposite=x
hypotenuse=10
3. Therefore, when you clear "x", you obtain:
Sin(62°)=x/10
(10)(Sin(62°))=x
x=8.82
How far up the wall does the ladder reach from the ground rounded to the nearest tenth?
The answer is: 8.82 ft
