The answer to this is to try the hardest you can! I believe in you :)
Answer:
Part A) 
Part B) 
Step-by-step explanation:
we know that
In a parallelogram, opposite angles are congruent and consecutive angles are supplementary
step 1
Find the value of x
we know that
----> by definition of parallelogram (opposite angles are congruent)
substitute the given values

solve for x

step 2
Find the measure of angle R

substitute the value of x

step 3
Find the measure of angle S
we know that
---> by definition of parallelogram (consecutive angles are supplementary)
we have

substitute



Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
Answer:
pls explain in more detail and attach pic cus ive got no clue what ur asking
Dividing the parallelogram in half and applying trigonometry is the easiest solution for me.
