It may be the last one......................................... but i'm not sure.
Check the picture below.
the radius, so-called because if we circumscribe the triangle in a circle, that'd be the radius of the circumcircle, is 3 inches, as you see there in the picture in red.
now, bear in mind that the triangle is an equilateral one, and therefore, 180/3 = 60, meaning all its interior angles are congruently 60°.
if we run the radius of the triangle, like there, it will cut one of those interior angles in half, namely the radius is an angle bisector, and if we run a perpendicular line to the bottom side, like the dashed one there, we end up with a 30-60-90 triangle, to which we can apply the 30-60-90 rule, as you see it there.
since we know what half of a side of the triangle is, as you see it there in blue, then we can use that and plug it in at
Answer:
4 h
Step-by-step explanation:
The resting spot was at the 8 mi mark.
When Stacey reached the 16th mile, they had covered
16 mi - 8 mi = 8 mi
They took 2 h for every 1 h, so

It may be easier to do this calculation on a number line. Each jump of 2 mi represents 1 h, and there are four jumps, so they took four hours.
The smaller number, x from the inequality x + 2x + 6 < 50 is x < 14.67
<h3>Inequality</h3>
x + 2x + 6 < 50
3x + 6 < 50
3x < 50 - 6
3x < 44
x < 44/3
x < 14.6666666666666
Approximately,
x < 14.67
Therefore, the smaller number, x is approximately x < 14.67
