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 result:

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

Solution:

c=16 ft a=14 ft  b=c2a2=162142=2 15=7.746 ft
sinA=a:c A=180πarcsin(a/c)=180πarcsin(14/16)=61.045=61242"
B=90A=9061.045=28.955=285718"
