If both are complementary then their sum will be 90°

\\ \sf\longmapsto m

\\ \sf\longmapsto 2x-10+x-2=90

\\ \sf\longmapsto 2x+x-10-2=90

\\ \sf\longmapsto 3x-12=90

\\ \sf\longmapsto 3x=90+12

\\ \sf\longmapsto 3x=102

\\ \sf\longmapsto x=\dfrac{102}{3}

\\ \sf\longmapsto x=34

Now

\\ \sf\longmapsto

Find the length of dm in the given fig.​
lesya692 [45]

Answer:

DM=12

Step-by-step explanation:

(Let the point where the altitude from D intersects AB be called as point E.) First, let's find the area of parallelogram ABCD. The area of a parallelogram is simply b*h=bh, where b is the parallelogram's base and h is the parallelogram's height. If we let AB and DE be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram ABCD will be AB*DE=15*8=120.

Now, how does this information matter, you might ask? Well, we can take either AB <em>or </em>CB to be the base and either DE or DM to be the height. In this case, let's take the latter two options, as we are looking to find the length of DM.

Therefore, we know that the area of parallelogram ABCD can also be found by calculating CB*DM. Since we know the values of the area and CB, we can write the following equation to solve for DM:

Area = CB*DM

120=10*DM (Substitute Area=120 and CB=10 into the equation)

\frac{120}{10}=\frac{10*DM}{10} (Divide both sides of the equation by 10 to get rid of DM's coefficient)

12=DM (Simplify)

DM=12 (Symmetric Property of Equality)

Hope this helps!

Answer:

So it makes sense that students would need more sleep, especially athletes. I think the conclusion should be that the data supported the hypothsis. Otherwise, students would have more injuries when they sleep, which is obviously not the case.

What is the equation of a line that contains the points (8, –3) and (–8, 3)?
DerKrebs [107]

Answer:

1. D y = 8

2. C y = −8

Step-by-step explanation:

1.Both points have y-coordinate 8, so the line is horizontal.

A horizontal line has equation y = k

where k is the y-coordinate of all of its points.

The y-coordinate of all points on this line is 8.

Answer: y = 8

2.A line with 0 slope is a horizontal line. All points on a horizontal line have the same y-coordinate.

A horizontal line has equation

y = k

where k is the y-coordinate of all of its points.

The y-coordinate of the given point is -8, so all points must have -8 as the y-coordinate.

Answer: y = -8
