Using pythagoras A squared + B squared = C squared to find out the slanted side of the triangle. Simular riangles. Side = 10.1 m. Then we used triganometry to find the angle from point to position using the SOHCAHTOA = which we decided was TAN = OPP\HYP which was 1.2 \10 = 0.12 then shift tan because it is an angle which gave us the answer of = 6.8 DEGREES. We could use SOHCAHTOA as it was a riht-angles triangle formation. This was for the smaller triangle, we then used SOHCAHTOA, to work out the larger traingle angle upward in the furthur corner, which helped us with the seating as the seats go up to that angle each time.
