Define the variable expression using the given information.The second angle of a triangle is 9° smaller than the first. The third angle is triple the size of the first angle. Define the variable expressions for the second and third angles using the variable x to represent the first angle.
What will be an ideal response?
x - 9 = second angle; 3x = third angle
