# 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:

$B=90-A=90-61.045=28.95{5}^{\circ }=2{8}^{\circ }5{7}^{\mathrm{\prime }}18\mathrm{"}$
