Vtriangle d e f is shown. angle e f d is a right angle. the length of e f is 24 and the length of d f is 7.
which trigonometric ratios are correct for triangle def? select three options.
sin(d) = startfraction 24 over 25 endfraction
cos(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 24 over 7 endfraction
sin(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 7 over 24 endfraction

75

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
