Answer:

This shape is a hexagon. Angles in a hexagon add to 720 degrees.

2(y) + 4(2y-20) =  720

2y + 8y-80 = 720

10y-80=720

10y=800

y=80

Let me know if this helps!

The length of rectangular field is 7 m less than 4 times the width. The perimeter is 136 m. Find the width and length
Elena-2011 [213]
P = 2(L + W)
P = 136
L = 4W - 7

136 = 2(4W - 7 + W)
136 = 2(5W - 7)
136 = 10W - 14
136 + 14 = 10W
150 = 10W
150/10 = W
15 = W <=== width is 15 m

L = 4W - 7
L = 4(15) - 7
L = 60 - 7
L = 53 <== length is 53 m

What is the answer to this equation. Please I really need help.
Anika [276]

Answer:

Angle A = Angle X

Line Segment CA = Line Segment ZX

Angle Y = Angle B

Line Segment YX = Line Segment BA

Step-by-step explanation:

Both triangles are stated to be equal so we can draw two triangles and label them. One triangle has Point A, Point B, and Point C. The second triangle has Point X, Point Y, and Point Z. Make sure that Point X on the second triangle is in the same spot as Point A on the first triangle (same for points B, C, Y, and Z).
