Make our unknown equal to x, in this case his current age.
In 20 years he will be three times as old as he is now, in other words:
x + 20 = 3x
Now solve the equation:
20 = 3x - x
20 = 2x
10 = x

We have been given that Jin cut a round gelatin dessert into 8 equal pieces. Seven of the pieces were eaten. We are asked to find the angle measure of the dessert that was left.
We know that there are 360 degrees degrees in a circle all the way around the center.
Since Jin cut all pieces of same size, so angle measure of all pieces will be equal.
To find the angle measure of each piece, we will divide 360 by 8.


Therefore, the angle measure of the dessert left dessert piece is 45 degrees and option D is the correct choice.
