Question on: WAEC Mathematics - 1997
The diagram above is a triangle XYZ whose area is 23.5cm2. XY =1Ocm and YZ = 8cm, calculate θ correct to the nearest degree.
A
34o
B
35o
C
36o
D
37o
Ask EduPadi AI for a detailed answer
Correct Option: C
Area = 1/2 x y x yz sinθ
23.5 = 1/2 x 10 x 8 sinθ
sinθ =
23.5 x 2/10 x 8 = 0.5875
θ = sin-1 0.5875 = 36o
θ = sin-1 0.5875 = 36o
