Question

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

Answer 1

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

○ C)
`\displaystyle 73°`

Explanation:

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

`\displaystyle 180° = 34° + 2m∠? → (146°)/(2) = (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.
