we know that

m∠PTS=m∠RTQ -----> by vertical angles

Step 1

m∠RTQ+m∠QTS=180\° -------> by supplementary angles

solve for m∠QTS

m∠QTS=180\°-m∠RTQ -------> equation 1

Step 2

m∠PTS+m∠QTS=180\° -------> by supplementary angles

solve for m∠QTS

m∠QTS=180\°-m∠PTS -------> equation 2

Step 3

equate equation 1 and equation 2

180\°-m∠RTQ=180\°-m∠PTS

-m∠RTQ=-m∠PTS

so

m∠RTQ=m∠PTS

therefore

<u>the answer is the option A</u>

Sum of the measures of angles RTQ and QTS is 180°

A grocery store sells a bag of 6 oranges for $2.34. If Mav spent $1.95 on oranges, how many did she buy?
poizon [28]

Answer:

5 oranges

Step-by-step explanation:

to solve this problem we need to make a cross-multiplication equation

2.34 is to 6 as 1.95 is to ?

? is the number of oranges that are needed to be found that were bought

2.34/6 = 1.95/?

Now we cross multiply 6 and 1.95 = 11.7

11.7/2.34 = 5

Give brainliest, please!
hope this helps :)
