<em><u>Answer:</u></em>
x = 8
<em><u>Step-by-step explanation:</u></em>
Okay, so with the info here, we know that angle RXS is 4x + 1, angle SXT is x + 9, and angle RXT is 50.
Angle RXT is angle RXS + angle SXT because it's on the diagram. So from
RXT = RXS + SXT, we can creat the equation:
50 = (4x + 1) + (x + 9) [Because we plug in the values]
So from here, we have to solve the equation:
50 = (4x + 1) + (x + 9)
First, we want to simplify everything so:
50 = 5x + 10
Then we want to isolate the variable so:
50 - 10 = 5x + 10 - 10
40 = 5x
40/5 = 5x/5
8 = x
<u>x = 8</u>
Call the sum S. Then, you can use the definition of percentage to obtain an equation to find the value of S: 1) 28% = 28 / 100; 2) 28% of x = (28/100)x; 3) that is equal to $100.80 => (28/100)x = 100.8 => x = 100.8 * 100 / 28 => x = 360. You can verify that the 28% of 360 is 100.80: 360 * 28/100 = 100.80. <span>Then, the answer is $360.</span>
