Answer:
longer side = √507 cm, shorter side = 13 cm
Step-by-step explanation:
sin60 = opposite side/26cm
opposite side = √507 cm
cos60 = adjacent side/ 26cm
adjacent side = 13 cm
longer side = √507 cm, shorter side = 13 cm
If PQ=7 and QR=10,
P=(7/Q) and R=(10/Q)
Therefore:
PR=(7/Q)(10/Q)
=(70)/Q²
Answer:
97
Step-by-step explanation:
I used the law of cosines: 
Let plug the numbers in : t^2=
which approx is 97 to the nearest inch.
To find how much gasoline costs each mile, you do 485/500. Reduce it to 97/100, or 97 cents. So .97m = c. B. Replace m with 1200 to get .97(1200) = c. C, after doing the math, you get 1164 dollars. C. Replace c with 820. Your equation is .97m = 820. Divide both sides by .97 to get m = about 845.36 to the nearest hundredth, 845.4 to nearest tenth, or 845 to the nearest whole mile. I recommend using the nearest hundredth to be precise, but that's up to you.
