Answer and Step-by-step explanation:
We are given a linear pair. The angles of a linear pair add up to 180.
<u>To find x, add the two angles together and equal it to 180, then solve for x.</u>
126 + x + 23 = 180
<u>Simplify.</u>
149 + x = 180
<u>Subtract both sides of the equation by 149.</u>
x = 31
<u>x = 31 is the answer.</u>

Answer:
For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:
A = (1/2)*H*(X + Y)
with this we can complete the table.
a)
Here we know:
X = 7cm
Y = 11cm
H = 6cm
Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2
b)
Here we know:
X = 8 m
Y = 10 m
A = 126 m^2
Then:
126 m^2 = 0.5*H*(8m + 10m)
126 m^2 = H*9m
126 m^2/9m = H = 14m
Then the height of this trapezoid is 14m
c)
Here we know:
X = 5mm
H = 8mm
A = 72 mm^2
Then:
72 mm^2 = 0.5*8mm*(5mm + Y)
72 mm^2 = 4mm*(5mm + Y)
72mm^2/4mm = 5mm + Y
18 mm = 5mm + Y
18mm - 5mm = Y
13 mm = Y
Then the parallel side 2 is 13 mm long.
Answer:
Unless I am an idiot here (think I am) it is AE s the length between A and E, so it is 8
Step-by-step explanation:
Every side of the square is 16.
A to E is half of a side of the square, not a full side.
So you divide 16 by 2, getting 8.
Hope this helps, and sorry if this seems sloppy, I am new to brainly :)
