Question

Calvin is using a 10 foot ladder to paint his house. If he leans the ladder against the

house so that it makes a 71° angle with the ground, how far up the house does the
ladder reach? Round to two decimal places. ​

Answer 1

9.46 ft

Explanation:

Law of sines

10/sin(90)=x/sin(71)

x=(sin(71)*10)/sin(90)

x=9.46
