Question

Ok i am not doin good with this stuff so if u can help that would be nice and thx

Answer 1

Step-by-step explanation:

we are dealing with an iscoceles triangle = 180°

Â= Č and AB = BC as given

angle B is 34° as given meaning angle A and C is going to be 73° ( 180° – 34° )= 73° your reason will be sides opposite equal angles are equal.

Hope this helped.

Answer 2

Answer:

○ C) $\displaystyle 73°$

Step-by-step explanation:

Isosceles triangles have two identical base angles, so you would do the following:

$\displaystyle 180° = 34° + 2m∠? → \frac{146°}{2} = \frac{2m∠?}{2} \\ \\ 73° = m∠?$

Sinse "?" represents the measure of BOTH C and A, because they are base angles, $\displaystyle m∠A$ is indeed 73°.

I am joyous to assist you at any time.
