Answer: K = 28^2, C = x^2, W = X^2, G = 22^2, T = X^2, and last but not least, A = X^2.

Step-by-step explanation:

For this you need to use the Pythagorean Theorem formula. A^2 + B^2 = C^2. Then you plug in your numbers. For this problem. You got figure out your As, your Bs, and last but not least, your Cs.

I hope this helps you solve the problem.

The period of this Ferris wheel can be calculated as 30 seconds. The amplitude is 25

<h3>How to solve for the period.</h3>

a. We have 60 seconds in a minute

In a minute it makes 2 rotations. The period = 60 secs / 2 rotations

= 30 seconds

b. We have h = 25 - 25cos \frac{25}{30} t

25 - 25cos\frac{25}{15} t

We would have the table in the attachment

d. Amplitude

= max - min / 2

= 50 - 0 / 2

= 25

 Provide the reasons for the proof. Given: RUMH is a rhombus. RUBM is a rhombus. Prove: RHM = UMB
MissTica

Here, RUMH and RUBM are two rhombus as shown in the diagram.

As, a rhombus has four equal sides,

so for RUMH, side RH = side HM = side MU = side UR

and for RUBM, side RM = side MB = side BU = side UR

As HM=UR and MB= UR , so we can write HM = MB

Now for two triangles ΔRHM and ΔUMB,

side RH = side MU

side RM = side BU

and side HM = side MB

'Side Side Side' theorem states that if three sides of one triangle are equal to three sides of another triangle respectively, then the two triangles are similar.

That means, ΔRHM = ΔUMB
