The number f of miles a helicopter is from its destination x minutes after takeoff is given by f(x)=60-1.5x. the number f of a mile a commercial jet is from its destination x minutes after takeoff is shown in the graph below. state the distance and length of time of each flight.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

you can not solvr this without numbers

answer is b 270°

i got it down for you chief.
