Answer in fraction form: x = 55/4
Answer in decimal form: x = 13.75
Both forms are equivalent, but they say it in a slightly different way.
===========================================================
Work Shown:
AC/QY = CD/YW
(x+5)/15 = 5/4
4(x+5) = 15*5
4x+20 = 75
4x = 75-20
4x = 55
x = 55/4
x = 13.75
------------
Explanations:
- The first step is possible because the polygons are similar. Similar figures have their corresponding sides be in the same proportion or ratio. Note how side AC has the double red angle (at point A) and a single red angle (point C). The side QY has the same idea in the same order. This is why AC corresponds to QY. The ratio AC/QY is the same as CD/YW.
- In the second step, I plugged in the expressions that the diagram shows. This is the substitution property.
- On step 3, I cross multiplied. The general format is A/B = C/D cross multiplies to A*D = B*C.

Mark got 20% raise for his salary. If this salary was $1800 what is the new salary?
So lets solve this!
Mark got 20% "raise" for his salary. It clearly indicates that it is percentage of increase, so therefore, after solving out all the sum, we would be adding up 1800 to get the total of the new salary.
Lets form this into statements ----
Percentage increase = 20%
Mark's old salary = $1800
Mark's new salary = 20 × 1800/100
Cancel out the zeros to make it more logical ----
20 × 18/1
= 360.
Now, we need to add 1800 and 360 to get Mark's new salary
1800 + 360 = $2160.
Mark's new salary is $2160.
Hope I helped :D
