Right triangle

Ladder 16 feet reaches up 14 feet on a house wall. The 90-degree angle at the base of the house and wall. What are the other two angles or the length of the leg of the yard?

Correct answer:

b =  7.746 ft
A =  61.045 °
B =  28.955 °

Step-by-step explanation:

c=16 ft a=14 ft  b=c2a2=162142=2 15=7.746 ft
sinA=a:c A=π180°arcsin(a/c)=π180°arcsin(14/16)=61.045=61°242"
