pos: 99.  Sor: 17.    roq: 64

Step-by-step explanation:

(5x+4)+(x-2)+(3x+7)=180

we add the angles to 180 because straight lines are equal to 180

5x+4+x-2+3x+7=180

5x+x+3x+4-2+7=180

9x+9=180

9x=

9x=171

x=19

then we plug x in

5(19)+4 +  (19)-2  +3(19)+7 = 180

angles (left right)

99.   17.     64.      

Step 1: find sale pricesale $= original $ - (original $ * sale %)= $42 - ($42 * 30%)concert % to decimal (30% ÷ 100)= 42 - (42 * 0.30)multiply in parentheses = 42 - 12.60= $29.40 sale pricestep 2: find total including tax using sale price found in step 1total $= sale $ + (sale $ * tax %)= 29.40 + (29.40 * 5%)convert % to decimal (5% ÷ 100)= 29.40 + 1.47= $30.87 total answer: yes, he has enough money. the sale price with tax only totals $30.87, so he has enough money because he has $35.00 to spend. hope this ! : )
