As this is triangular height and floor length we multiply and divide by 2 (representing halving the square)
= 3.5 x 6= 19 19/2 = 9.5ft
To thereafter measure the angle we can see 9.5/3.5 =2.711
so we have 90, 27 and 63 degree.
As this is decimal we round up to 30 degree. and round down to 60 degree.
