One angle is five less than three times the size of another angle. Together they have a sum of 143 degrees.

What are the sizes of each angle?

let the another angle be x ,then first angle will be 3 x-5 according to the question x + 3 x-5 =143' x+3 x=143+5 4 x=148 x=148/4 x=37' another angle = x =37' first angle = 3x-5 = 3*37-5 = 111-5 = 106'

Let the size of one angle be x so the size of another angle = 3x-5 sum of the two angles = 143 degrees so, x + 3x - 5 = 143 or, 4x = 143+5 or, x = 149/4 = 37.25 degrees other angle = 3*37.25-5 = 106.75 degrees

The first angle is 37 degrees, and the second angle is 106 degrees. This satisfies the condition that one angle is five less than three times the other, and they add up to 143 degrees. By solving the equation step-by-step, we arrive at these values.
