If you are using Cosine and need to solve for an unknown hypotenuse, you should...


a) multiply cos(angle) by the adjacent side

b) divide the adjacent side by cos(angle)

c) add all three angle measures

d) add the angle and the side length


Sagot :

Using cosine, we can find the hypotenuse by using the formula below;

hypotenuse = adjacent / cos ∅

Trigonometric ratios:

  • Trigonometric ratios are ratios of sides of a right angled triangle.
  • The simplest ratios are cosine, sine and tangent.

Using cosine, the hypotenuse side can be solved as follows:

cosine ∅ = adjacent / hypotenuse

cross multiply

hypotenuse cos ∅ = adjacent

divide both sides by cos ∅

hypotenuse cos ∅ / cos ∅ = adjacent / cos ∅

Therefore,

hypotenuse = adjacent / cos ∅
