Answer:
Exterior angle to be used for parking is 72°
Step-by-step explanation:
I've attached an image of a paralelogram.
Now, we are told that from the outside it looks like a parallelogram with one of the interior angles as 108.
This means that the bigger angle internally would be 108°
Which from the attached image is angle B internally or angle D internally.
So, the interior angle observed will be either at point B or D on the parallelogram.
Now, the sum of angles on a straight line is 180°
Thus,
Internal angle D + External Angle D = 180
Or
Internal angle B + External Angle B = 180
Internal angle is 108°
Thus;
External angle for either B or D = 180 - 108 = 72°
So the exterior angle to be used for parking is 72°

Step-by-step explanation:
10 in 10 places is 100. 10*1=10. 10*2=20..10*3=30.10*4=40,. 10*5=50,10*6=60,,,10*7=70,,. 10*8=80,. 10*9=90,. 10*10=100.
Answer:
x = 13y + 0.625
Step-by-step explanation:
4(2x - 3y) = y + 5
8x - 12y = y + 5
8x = y + 5 + 12y
8x = 5 + 13y
8x ÷ 8 = 5 + 13y ÷ 8
x = 5 + 13y ÷ 8
x= 13y + 5 ÷8
x = 13y + 0.625
