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 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
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'
