Answer:

The value of m ∠BCD is 120 degrees

Properties of a parallelogram

The properties of a parallelogram;

Opposite sides are congruent AB = DC

Opposite angels are congruent D = B

Consecutive angles are supplementary, that is, the sum up to 180

The diagonals of a parallelogram bisect each other

If AB = DC

Then, we have;

2x + x + 2x + x = 360

collect like terms

6x = 360

Make 'x' the subject

x = 360/6

x = 60 degrees

But m ∠BCD = 2x = 2 (60) = 120 degrees

Thus, the value of m ∠BCD is 120 degrees

At the movie theater Leon can buy 4 large popcorns or 2 large popcorns and 3 candy bars for the same price. If the candy bars co

AlexFokin [52]

4p = 2p + 3c....p = popcorn, c = candy bars
c = 6

4p = 2p + 3(6)
4p = 2p + 18
4p - 2p = 18
2p = 18
p = 18/2
p = 9......whoa....9 bucks for popcorn....nothing is cheap anymore

For the following right triangle, find the side length . Round your answer to the nearest hundredth

vlada-n [284]

Step-by-step explanation:

Since we have 90° angle that means that side opposite of it is hypotenuse, so it goes:

a=10cm b=6 c=?

${a}^{2} = {b}^{2} + {c}^{2}$

${10}^{2} = {6}^{2} + {c}^{2} \\ \\ 100 = 36 + {c}^{2} \\ \\ {c}^{2} = 100 - 36 \\ \\ {c}^{2} = 64 \\ c = \sqrt{64} \\ c =8$

-9 – 9u = -3u + 9 last one for today

Yakvenalex [24]

-9u + 3u = 9 + 9
-6u = 18
u = -18/6
u = -3
Thus, u is equal to -3

I think it is 1.9cm each because 7.75 divided by 4 equals that (1dp)
