Alright, Part A.
This would be 5x + 4x + 5x +4x = 360. This is because all the angles in a parallelogram add up to 360. The other two angles are not unknown, as they correspond with the known angles of 4x and 5x, thus we get all angles.
So add all angles together and we get 18x = 360. We then do x =360/18, thus x = 20. So the answer is C.
Now for the angles, we will have to do the value of the x (which is 20) multiplied by the coefficient (the number in front of the x). So we do 20*4 = 80 and 20*5 = 100. So the answer must be C.
Answer:
C

It's the only scatterplot that has a strong linear relationship.
In easier terms, it's in a straighter line than the other graphs.
I hope this helps!
Answer:
52.5
Step-by-step explanation:
Since this is an isosceles triangle, the base angles are the same
The three angles add to 180
R+ T + S = 180
3x+30 + 3x+30 + 12x-15 = 180
Combine like terms
18x +45 = 180
Subtract 45 from each side
18x+45 - 45 = 180-45
18x =135
Divide each side by 18
18x/18 = 135/18
x = 7.5
We want angle R
R = 3x+30
= 3( 7.5) +30
22.5 +30
52.5
