Answer:
Step-by-step explanation:
The car uses 15 gallons of gasoline to drive 420 miles.
(15 gal)/(420 mi) = 1/28 gal/mi
The car uses 1/28 gallon of gasoline per mile.
y = mx + b
When x = 0, at the start of the drive, the car has 15 gallons of gasoline.
y = mx + 15
Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

Let the lengths of sides of the triangle be 3x, 6x and 8x
Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.
In this situation triangle BOC is inscribed in the circle. Length of BC is 10,91, length of BO is 5 (radius) and length of CO is 5 (radius).
