Step-by-step explanation:

Cosine is a trigonometric function that is represented by adjacent divided by the hypotenuse. The side adjacent to angle A is AC and the hypotenuse is AB, so we can say cos(A) = . We can do the same for angle B. The side adjacent to it is BC, and the hypotenuse is again AB. So, we can say

cos(B) = . We are solving for , so we can substitute the value of those two and solve:

AC is given to be 3 and BC is also 3, so is which is just 1.

the answer is 8
