Answer:
b = 11 (or 11.25)
Step-by-step explanation:
From the diagram,
b = 15 - a
Since the triangles in the figure are all right angled, apply the appropriate trigonometric function to first determine x. We have;
Sin θ =
Sin 30 =
x = Sin 30 x 15
= 7.5
x = 7.5
To determine a,
Cos θ =
Cos 60 =
a = cos 60 x 7.5
= 3.75
a = 3.8
b = 15 - 3.75
= 11.25
b = 11
