Question 110076
The hypotenuse is the base of the triangle.
the altitude divides the 90 deg angle 3:2 also 54:36 deg.
tan(36)=x/18
x=18tan(36)=13.0778'
x=18tan(54)=24.7749'
hyp=13.0778+24.7749=37.8526'=37'10"
short side: 18^2+13.0778^2=495.028
sqrt(495.028)=22.2492'=22'3"
long side: 18^2+24.7749^2=937.794
sqrt(937.794)=30.6234'=30'7"
Check:
22.2492^2+30.6234^2=1432.82
sqrt(1432.82)=37.8526' hyp
