Hello, please help i’ll give u okayyy ly <3

Step-by-step explanation:

Isoceles triangle.

It is a isoceles triangle since we know that one triangle angle measure is 80 we can solve the rest.

Since line AB and CD is parallel and line AC is the transversal, Angle A measure is 50 via the alternate interior angle postulate.

We can then using the triangle interior theorem to find the third angle.

80+50+x=180

130+x=180

x=50

So the third angle measure is 50.

Using the definition of a isoceles triangle, the triangle has two congruent measures so it is a isoceles triangle.

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
