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
