Answer:
c=18
Step-by-step explanation:
Put all like terms to one side:
c=54-36
Simplify:
c=18
Here it is listed from greatest to least:
56.32, 56.321, 56.2
Answer:
60
Step-by-step explanation:
Since the sides are equal, the angles have to be equal
The angles of a triangle add to 180
180/3 = 60
Angle A = 60

is differentiable across its domain, so the MVT says there is some value of

in the open interval

such that

You have

so the equation above becomes

Solve for

.




so

is indeed the average of the endpoints, i.e. the midpoint.
