Answer:

"Let's say it is equal to 45 degrees, or π/4. Calculate the arc length according to the formula above: L = r * Θ = 15 * π/4 = 11.78 cm . Calculate the area of a sector: A = r² * Θ / 2 = 15² * π/4 / 2 = 88.36 cm² . You can also use the arc length calculator to find the central angle or the radius of the circle. "

7m+2=7n−5

Swap sides so that all variable terms are on the left hand side.

7n−5=7m+2

Add 5 to both sides.

7n=7m+2+5

Add 2 and 5 to get 7.

7n=7m+7

Divide both sides by 7.

7

7n

=

7m+7

Dividing by 7 undoes the multiplication by 7.

n=

7

7m+7

Divide 7+7m by 7.
