Answer:
B. 22
Step-by-step explanation:
We know tan60=

Let common side be x
Tan = opp/adj= sqrt(3)

Transposing we get :

Now, we know that since the other triangle is a 45-45-90 triangle, we can state that the side adjacent to the given angle = 11 sqrt(2) as the two sides are equal due to the triangle being an isoceles triangle.
Solve for x by using Pythagorean theorem:



Hence answer is B. 22
They are not
It goes from
0/0 1/3 2/5 3/6(or 1/2) which are not the same. This makes them not proportional to one another. (I think)
