Question

Please help me thank you.

Answer 1

Question 1:

When using a ratio that is comparing two parts of one whole thing, I like to use this approach.

The ratio is 11:25

Add 11 and 25.
You get 36.

Now, just divide that from 180 (the total number of degrees in a straight line)

180/36 = 5

Multiply that with 25. (the ∠ZXY part of the ratio)

5 * 25 = 125.

Thus, angle ZXY is 125 degrees.

Question 2:

Let x be a variable.

The length is 5x and the width is 4x (using the ratio and assuming the length is larger than the width).

We know that 5x multiplied with 4x is 500.


`5x(4x)`


`=20x^2`

Now, we have an equation


`20x^2=500`

Divide both sides by 20


`x^2=25`

Now, take the positive square root.


`x=5`

Now, multiply that by 5 (the length part of the ratio).

5*5 = 25.

That's your answer.

Have an awesome day! :)
