Ladder slope

What is the slope of a ladder 6.2 m long and 5.12 m in height.

Result

A =  55.67 °

Solution:

c=6.2 m a=5.12 m A1=arcsin(a/c)=arcsin(5.12/6.2)0.9716 A=A1 =A1 180π  =55.67034  =55.67=554013"c=6.2 \ \text{m} \ \\ a=5.12 \ \text{m} \ \\ A_{1}=\arcsin(a/c)=\arcsin(5.12/6.2) \doteq 0.9716 \ \\ A=A_{1} \rightarrow \ ^\circ =A_{1} \cdot \ \dfrac{ 180 }{ \pi } \ \ ^\circ =55.67034 \ \ ^\circ =55.67 ^\circ =55^\circ 40'13"
