A mother is 30 years older than her son. Fifteen years ago the son was 1/3 of his mother's age. How old is each now?

Let s be the son's age 15 yeasr ago and m the mother's age that year.

We also know that:

Plotting vallues:

Remember that they were that age 15 years ago.

So their actual age is 30 and 60.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

goog may be able to you find that answer
