Solve for m/TRS if m/QRS = 88° and m/QRT = 54°.<br> ?<br> Answer: m/TRS =<br> Submit Answer
Citrus2011 [14]

The measure of the angle TRS is 34 degrees

<h3>Line and angles</h3>

The point where two lines meet is known as an angle

Given the following parameters

<QRS = 88 degrees

<QRT = 54 degrees

Using the expression

<QRS = <QRT + <TRS

Substitute the given parameters

88 = 54 + <TRS
<TRS = 88 - 54

<TRS = 34 degrees

Hence the measure of the angle TRS is 34 degrees

A 15% discount saves you $5 off the price of an electronic game. How much do you save off the regular price if the discount is w
chubhunter [2.5K]

Answer:

The 45% off discount saves an additional $10 compared to the 15% discount for a total of $15 off regular price.

Step-by-step explanation:

We can find the original price of the game through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio  of $ to $. Since 15% of 100% is the same ratio as $5 to the unknown original $ price, I write:

\frac{15}{100} =\frac{5}{y}

I can now cross-multiply by multiplying numerator and denominator from each ratio.

15y=100(5)\\15y=500

I now solve for y by dividing by 15.

\frac{15y}{15} =\frac{500}{15} \\y= 33.33333....

The original price was $33.34.

Now, we can find the amount if 45% off and then then compare the two discounts. To find the percent off I can multiply by 0.45(33.34)=15. The 45% off discount saves an additional $10 compared to the 15% discount.
