Question

In the triangle below, if < A = 43 °, what is the measure of < C?

Answer 1

Answer:

b. 43°

Explanation:

The triangle ABC is an isosceles triangle because AB = CB. Now one property of isosceles triangles is that base angles A and C are also equivalent. In other words,

$∠A=∠C$

Now we are told that

$∠A=43\degree$

Therefore,

$\angle C=\angle A=43\degree$$\Rightarrow\boxed{\angle C=43\degree.}$

The measure of ∠C is 43°. Therefore, choice B is the correct answer!
