Two fences in a field meet at 120 degrees. A cow is tethered at their intersection with a 15-foot rope, as shown in the figure.
bija089 [108]

Answer:

Area of the field that the cow graze  = 235.71 sq. ft

Step-by-step explanation:

Area of the field that the cow graze = (120 / 360) * πr²

   = (1/3) * (22/7) * 15 * 15

   = (22 * 5 * 15) / 7 =  1650 /7

   = 235.71 sq. ft

Can someone please help me out with this its really urgent Ill mark brainliest
Alex73 [517]

Answer:

smart dot company c=.50t+12

communication plus c=2.50t

Step-by-step explanation:

smart dot has the starting point of $12 per month already so that would be your y-intercept with the equation being y=mx+b , y being the cost m being the amount of money per hour, x being the time spent, and b being the starting cost.

So with that smart dot would be c=.50t+12

with communication plus not having that starting point it would just be c=2.50t

Triangle ABC is congruent to triangle DEF .
svetlana [45]

Answer:

\boxed{m\angle A = m\angle D}\\

Step-by-step explanation:

When you use a congruence statement, you must line up the corresponding parts of the triangles.

BC = DE is wrong, because BC = EF.

\boxed{m \angle A = m \angle D} is correct.

m∠B = m∠F is wrong, because m∠B = m∠E.

AC = EF is wrong, because AC = DF
