Question

The diagram shows a right angled triangle 13cm, 24 degrees, what is the value of H?

Answer 1

Answer: h=11.9

Explanation:

We know that the hypotenuse is 13 and we have the adjacent side of the angle 24. This means we can use cosine to solve.

`cos(x)=(adjacent)/(hypotenuse) \\cos(24)=(h)/(13)`

Multiply both sides by 13 to isolate h

`cos(24)=(h)/(13) \\(13)cos(24)=(h)/(13)(13)\\13cos(24)=h`

h=11.9
