On a recent 160 mile road trip claires car used 7.75 gallons if gas how many gallons should she expect to use on a 150 mile road trip

Ok so,

160 divided by 7.75 = 20.65

therefore,

150 divided by 20.65 =  7.265625 gallons or 7.27 (2 d.p)

The relations ship of the circle and triangle is that a ngles and points on the circumference of a circle are the same thing. a point on the unit circle is the same as a right triangle formed by a radius to the point and its perpendicular to the x-axis. hence sines and cosines which come from ratios of legs of a right triangle to the length of the hypotenuse are also the coordinates of the point on a circle of radius one. i hope this would you.
