Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)

==================================================

Work Shown:

If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.

Let's solve for x

4x-30 = 2x

4x-2x = 30

2x = 30

x = 30/2

x = 15

Answer:

The width of Dana's living room is 16 feet.

Explanation:

Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.

For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:

Answer:

15000

Step-by-step explanation:

0.4%=0.004

0.004x=60

x=60/0.004

x=15000

The number 60 is 0.4 percentage of the number 15,000

Given data ,

To find the number that 60 is 0.4% of, we can set up the equation:

60 = 0.4 percentage of x

To solve for x, we need to convert 0.4% to its decimal form, which is 0.004:

0.004 * x = 60

Now we can solve for x by dividing both sides of the equation by 0.004:

x = 60 / 0.004

Dividing 60 by 0.004 gives us:

On simplifying the equation , we get

x = 15,000

Therefore, 60 is 0.4% of 15,000.

Since 0.4% is a very small percentage (less than 1%), we would expect the answer to be a lot greater than 60. This is because when a small percentage is applied to a number, the result will be significantly larger than the original number. In this case, the number that 60 is 0.4% of is 15,000, which is a lot greater than 60.

Answer:

162

Step-by-step explanation:

a=[tex]\frac{a+b}{2} h[/tex]

a=base and the base is 13 ft.

b= also means base which is 23 ft.

h= height which is 9 ft.

so 13+23 is 36

36/2 is 18

and 18 times 9 is 162

Answer:

C. mass

Step-by-step explanation:

gravity is different on the moon

and weight is different because of that change in gravity

If the bowling ball is placed on the moon, the feature which will stays same,  mass of the ball. So option C is correct

The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.

Given that,

A bowling ball is placed on the moon

So, when ball is placed on moon, it affects the following factors,

Force from gravity - On the Earth and on the Moon the gravitational force will be different.

Weight - On the Earth and On the Moon the gravitational acceleration will be different so weight will be different on both the planets.

Mass- It is the property of the object and it is independent from the planets, it will be same on every planet.

Hence, the  Mass is same on both the planets
