Help basic polygon in the diagram, ABCD is a straight line. calculate the value of X and Y. Will mark as brainliest ✓

Okay! So for this we need to realize a few things!

First the triangle CDE is an Isosceles triangle, thus two of the side angles (the non ) are the same value! That means that angle:

°

Which means that:

°

Now that we know what angle ECD is, we know that angle BCE is equal to:°

Lastly we know that angle are similar due to parallel lines, thus:

°.

Therefore:

°

°

i think it would be 43 movies that would have to be watched.

step-by-step explanation:
