23. The sum of the interior angles of a triangle is equal to 180°. The angles are to be identified as angles A, B and C. One of the angles is 20° larger than the smallest angle, and the third angle is 10° larger than the smallest angle. Calculate the size (in degrees, °) of each of the three angles in this triangle.
28. The sum of two numbers is 30. Twice the larger number is 3 less than 7 times the smaller number. What are the numbers?
