Question

How do I find missing the exact values of these questions?

Answer 1

Given a right angle triangle

The hypotenuse = 16

Side BC represents the adjacent to the angle 60

So,

`\begin{gathered} \cos 60=(adjacent)/(hypotenuse) \\ \\ \cos 60=(BC)/(16) \\ \\ BC=16\cdot\text{cos}60=16\cdot(1)/(2)=8 \end{gathered}`

So, the answer will be BC = 8
