Question

question 20 of 45 in the triangle below, what is the length of (overline{bc})? a. 12 b. 24 c. 46 d. 92

Explanation:

Step1: Identify triangle type

Since $\angle A = 46^{\circ}$ and $\angle C=46^{\circ}$, the triangle is isosceles. In an isosceles triangle, the sides opposite the equal - angles are equal.

Step2: Determine side length

The side opposite $\angle A$ is $BC$ and the side opposite $\angle C$ is $AB$. Given $AB = 12$, then $BC=12$.

Answer:

A. 12
