Answer: a) parallelogram
Step-by-step explanation:
Top side and bottom side are same lengths/parallel
Angles in a quadrilateral add up to 360 degrees
105+75*2=360
Answer: -4
Step-by-step explanation:
Set up an equation
8x+3=-29
Subtract 3
8x=-32
x=-4
Answer:
The angle at B is the same as the angle at E so equate them to each other to find x
2x+4=40°
2x=40-4
2x=36
x=36/2=18
Step-by-step explanation:
Hope this is helpful! stay safe and God Bless:)))
Answer:
I. x + y = -3 --> y = -x - 3
II. y = 2x
2x = -x - 3
3x = - 3
x = -1
y = 2*(-1) = -2
