Remember SOHCAHTOA for right triangles?

a) Cos (B) = 8/17 now do th einverse cos to find B

b) Sin 20 = ?/11 Can you do it now?

c)Tan GHJ = 10/3

d) Pythagorean theorem DIagonal = sqrt (10^2 + 3^2)

e) draw line from S to bisect side 10 then 1/2 Diagonal is hypotenuse and one leg is 5 then calculate the top angle....which is 1/2 of angle HSI

See what you find!
