30 60 90 triangles have a peculiar theorem to them. That’s why they’re known as special right triangles, and they’re super easy to solve. For whatever the length of the shortest side is, which we’ll call Z in this case, the length of the hypotenuse is always 2*Z, and the length of the adjacent side is always Z * sqrt3. In the context of this problem, that means that y = 16 and x = 8sqrt3.
The equation the find the circumference of a circle is c=2<span>πr.
c=2</span><span>π5
c=10</span><span>π
c=31.4159...
the circumference of the backyard is 31.4 yards.
Hope I helped...</span>
M=1.53 -> Multiply 5.1 by .3 and you find m.
you need to get a common denominator
the common denominator is 40
3/8 * 5/5 = 15/40
2/5 * 8/8 = 16/40
25 15/40 < 25 16/40 so Karen rode farther
