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.

34^o

B.

35^o

C.

36^o

D.

37^o

E.

40^o

Correct answer is 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 = 36^o
