Answer: B. 55
Step-by-step explanation:
You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.
---------------------------------------------------------------------------------------
Given
(2x+15)+x=180
Expand parenthesis
2x+15+x=180
Combine like terms
3x+15=180
Subtract 15 on both sides
3x+15-15=180-15
3x=165
Divide 3 on both sides
3x/3=165/3
x=55
Hope this helps!! :)

Answer:
55
AB // DC
∠B + ∠C = 2x + 15 + x = 180
3x = 165
x = 55
(2/3, 17/3)
put x and y coordinates value in given equation to check equality. it equality holds that's the coordinates we are looking for.
here 2nd coordinate holds the equality
The correct option is G.Hope this help!!
C is the closest estimate
