Let the unknown number be x
Sin = opp

Sinx°=9/20
Sinx°=0.45
Divide both sides by sin
Sinx°=0.45
Sin Sin
x°=0.45
Sin
x=sin raise to power -1,0.45
x=26.7
x=27° to the nearest degree.

Let the unknown number be x
Tan x⁰= 9/20
Tan x⁰ =0•45
Divide both sides by tan
Tan x°/tan=0•45/tan
x°=tan raise to power-¹0•45
x=26•7
x=27°
Tan x⁰= 9/20
Tan x⁰ =0•45
Divide both sides by tan
Tan x°/tan=0•45/tan
x°=tan raise to power-¹0•45
x=26•7
x=27°

To the nearest degree, the angle the ladder makes with the wall is 27°.
