CAN SOMEONE PLEASE HELP ME WITH MY MATH CLASS PLEASEEE

Step-by-step explanation:

Recall that the addition of all 4 internal angles of a quadrilateral must render . Therefore, since you are dealing with a parallelogram (notice the sides that are congruent AB = DC, and BC = AD) also you have that opposite angles in the parallelogram must be equal. This means that angle equals angle =

Now, angles and must also equal each other, so, using the sum of all angles equal to , we have:

-50/3

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
