A car travel 35 miles on 3 gallons of gasoline. How many gallons of gasoline will the car need to travel 150 miles?

12.857

Step-by-step explanation:

. you divide 3 by 35 in order to find out how many gallons are used in a mile

. then multiply the number you get by 150 because the number you get is equal to 1 mile and u are finding for 150 miles

. lastly you round your answer (optional) ( i rounded to 3 dp's)

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
