Question

I HAVE LIKE 2 MORE QUESTIONS, HELP ME PLZ!

Answer 1

Given:

Base length of triangle = 10 units

Height of triangle = $\sqrt{44}$ units

Length of hypotenuse of triangle = 12 units

To find:

Exact value of Cos A

Steps:

The cosine of any angle is equal to the length of the adjacent side by the length of the hypotenuse side.

So,

Cos A = $\frac{adjacent}{hypotenuse}$

Cos A = $\frac{10}{12}$

Cos A = 0.833

Therefore, the exact value of cos A is 0.833.
