Answer:

We first have to find the volume of the cube: (0.3 * 0.3 * 0.3) we then get 0.027, then we plug in the numbers for the density formula. D = 18.954/0.027 will give us 702.

Can someone PLEASE explain in simple terms which trigonometric ratio to use, like tangent, cosine, or sine, and WHY?
natulia [17]

Answer:

Use law of Cosines or Tangent

Step-by-step explanation:

This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.

However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:

c=a^2+b^2﹣2abcos(angle number).  But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2

The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.

Hope this helps :)

Parallelogram H G J L is shown. Diagonals are drawn from point H to point J and from point G to point L and intersect and point
Ghella [55]

Answer:

50 units.

Step-by-step explanation:

It is given that HGJL is a parallelogram and diagonals intersect each other at point K.

HK=c-7,JK=3c-33,GK=c+12

We now that diagonals of parallelogram bisect each other. So,

HK=JK

c-7=3c-33

33-7=3c-c

26=2c

Divide both sides by 2.

13=c

Now,

GK=c+12=13+12=25

Diagonals of parallelogram bisect each other. So,

GL=2(GK)=2(25)=50

Therefore, the measure of GL is 50 units.
