X = 7. Because both lines equal the same so it has to equal 75
11 x 7 = 77
77-2 = 75
X = 7
Answer:
DE = about 41.843 (rounded to nearest thousandth)
EF= 34.276 (rounded)
Step-by-step explanation:
For DE, we know that the shorter side (the opposite side) is 24, while the angle across form it is 35°. We can use trigonometry to figure this out. SinФ equals the opposite side (in this case, 24) divided by the hypotenuse. Set sinФ equal to a ratio of the sides like this:
sin(35) =
x represents the hypotenuse length, which we don't know; 35 is the angle measure. Next, isolate x so that the equation looks like this:
= x
You will need a calculator for the next part. (and make sure you're in degree mode!). evaluate sin(35) and divide 24 by that value. That is DE's length. DE = about 41.843 (rounded to nearest thousandth)
For EF, we can just use Pythagorean theorem now that we know the other sides' values.
EF^2 + 24^2 = DE^2
*a calculator might also be useful for this part.
EF= 34.276 (rounded)
Answer:
5
Step-by-step explanation: BECAUSE IN A PARALLELOGRAM OPPPOSITE SIDES ARE EQUAL SO IF THE PERIMETER IS 33.2 WE SHOULD SUBTRACT THAT NUMBER WITH 11.6*2 WHICH IS 23.2 SO 33.2-23.2 WHICH IS 10,SO 10/2 IS THE OTHER SIDE OF THE PARALLELOGRAMWHICH IS NOTHING BUT 5
