Question

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

Answer 1

b. 43°

Step-by-step 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!
