Answer : 7.5 ft
Step-by-step explanation:
when the length of the shadow is 8ft, the actual height of the man = 5ft
8:5
let the giraffe be 'x' ft tall.
if the length of the shadow is 12ft, actual height = x ft
12:x
8:5 x 12:x
× 
x=
x=7.5 ft
Therefore, the giraffe is 7.5ft tall.

Answer:
B= 44.9506°
Step-by-step explanation:
WE apply sine angle formula

Given angle C = 51, c= 11 and b = 10

Plug in the values

Cross multiply it
10 * sin(51) = 11* sin(B)
7.771459615 = 11 sin(B)
Now divide by 11 on both sides
0.706496328 = sin(B)
Now 
B= 44.9506°
