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!
Hi thanks for the reply! But I'm super confused at your answer for b. Shouldn't it be 11*tan(20) instead of sinus?
