Step-by-step explanation:

D is the 90° angle and d=15 is opposite of the angle of the same letter. The triangle's other corners are E and F, and the sides corresponding to those angles are opposite of them too.

Angle F = 35° and E= (90-35)°= 55°. Then you could use something like the Law of Sines to find the sides if you wanted as well.

The length of the rectangle is twice its width. Write and solve a system of linear equations to find the length L and width W of
vazorg [7]

Answer:

The length is equal to 12 and the width is equal to 6.

Step-by-step explanation:

In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.

2L + 2W = P

2(2x) + 2(x) = P

4x + 2x = 36

6x = 36

x = 6

Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than it length. Find the length a
lesya [120]

P = L + L + w + w

72 = 2(L) + 2(L-4)

Distribute

72 = 2(L) + 2(L) - 8

Add like terms

72 = 4(L) - 8

Subtract 8 from both sides

64 = 4(L)

Divide both sides by 4

16 = L

The length is 16. Now substitute that in the equation for finding w.

w = L - 4

w =

Need help with number 43 and 45 and need to show the work
Alex787 [66]
43:
       Negative temperatures are basically the same as normal ones, although they go below zero, so they are still the same distance apart from zero, just on the left side of the number line.

      To find the answer find the difference between 30.5°C and 0 (which is 30.5).

      Next, find the difference between -122.2°C and zero (122.2)

       Finally, add 122.2 + 30.5 to find the total distances from the zero combined for the full distances apart from each other.

     (We add them because -122.2 to the left of zero, and 30.5 is on the right)

      You should get 152.7 as your answer.

45:
     I'm guessing since it is asking for the deepest point (-5315) from sea level (0), the answer is -5,315 feet

     *Remember 5,315 is negative because numbers below sea level are all negative*

     So the answer should be -5,315 feet deep. (I'm not sure how to show your work for that I'm guessing it is 0 - 5,315 at the slightest).

 *Hope this all helped :)*
