Major arc jl measures 300°.

which describes triangle jlm?

a. right
b. obtuse
c. scalene
d. equilateral

This is how i know its D  

It is given in the question that measure of the major arc is

Implies that

Also,  (complete angle)

Putting the value we get

On solving we get

Now in triangle JML

MJ=ML (radius of the circle)

Therefore,

(Angle opposite to equal sides are equal)

Using angle sum property of a triangle that sum of angles of a triangle is

On solving

Therefore all angles of triangle JML are equal to 60 degree

Hence the given triangle is Equilateral triangle

Answer is option D

in 4 days he will run   12/14

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
