Answer:
4√3
Step-by-step explanation:
For isosoles triangles the legs are congruent
v = u
--------------------
using the pythagorean theorem
(4√6)² = v² + v²
(16 * 6) = 2v²
Divide both sides by 2
16 * 3 = v²
Take the square root of both sides
4√3 = v
A = 8B
A + B = 180
8B + B = 180
9B = 180
B = 20
A = 8 * 20 = 160
Answer: 12 units
