Answer:
rhombus; Measure of angle B = 70 degrees
Step-by-step explanation:
The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.
110 + B = 180
B = 180 - 110
B = 70
It is a rhombus because all sides are equal.
Let x or y be 0
4x-2y=5
4(0)-2y=5
-2y=5
Divide -2 and 5 by -2.
y=-2.5
4x-2y=5
4x-2(0)=5
4x=5
Divide 4 and 5 by 4.
x=1.25
