Question

how to find the missing side of a right triangle if you are giving the h and 40 degrees

Answer 1

is h the hypotenuse?

Answer 2

yes

Answer 3

Then there are two missing sides.

Answer 4

We know h = 40

But we also know it's a right triangle.

So, what can you conclude from this? Note, that the degrees of a triangle will add up to 180.

So, what does your second degree equal? (Hint: It's a right triangle, therefore, one degree must be?)

Answer 5

So you could say: sine 40 = side opposite 40 degree angle/hypotenuse
And cosine 40= side adjacent 40 degree angle/hypotenuse
