Using an indirect proof:
Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.
Answer:
83
I know because I did this problem a few years ago
2.70g = c
you have 2 gallons so it would be 2.70(2)=5.40
gallons - g
cost - c
Total awpaws and guavas sold in a week = 328
Let the number of pawpas and guavas be x
ATQ
3x + 5x = 328
8x = 328
x = 328/8
x = 41
Pawapas in a week = 123
Guavas in a week = 205

Answer:
8 Minutes
Step-by-step explanation:
since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.
666-562 = 104
Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.
104 / 13 = 8
