Answer:

D. The parallel bases remains parallel

Step-by-step explanation:

Reflection is an example of solid transformation in which an object is turned about a line or point to produce its image. Though the initial orientation of the given object changes, but its shape and size is preserved.

A trapezoid is a quadrilateral. If it undergo reflection across the x-axis, then y-axis; its parallel bases would remain parallel. Though the initial orientation of the trapezoid would have changed.

Question 1 of 10

Zanzabum

Answer:

A: 40 degrees

Step-by-step explanation:

Since every triangle is 180 degrees, you can start off by subtracting 50 from 180 since that side does not contain a y for you to solve.

Since the other two sides do have a y in them, you would set 130 degrees equal to y+10 and 2y:

130=y+10+2y

Then you would isolate the y's by subtracting 10, and you would add y and 2y together to get:

120=3y

Finally, you would divide 120 by 3 to get your answer, 40=y.

Hope this helps!

Sathish is going on a 2000 kilometer road trip with two friends. The car consumes 6 liters of gas for every 100 kilometers, and

6*1.20 is the cost in dollars per 100 kilometers. If each friend pays for one third (666.66 repeating kilometers), then they would have to pay (6*1.20)*6.66 repeating which equates to $48 per person and $144 total.
