Use a variable (x) for the smallest angle (call it angle 1). Angle 1 = x The second angle is twice the smallest angle (2x) The largest angle is 6 times the smallest angle (6x) Take the sum of all three of those angles and make an equation, equal to 180. x + 2x + 6x = 180 9x = 180 (combined like terms) x = 20 (divide by 6) Angle 1 (x) = 20 Angle 2 (2x) = 40 Angle 3 (6x) = 120
Let's say that x is the smallest angle. This equation could be used to solve for the smallest angle: x + 2x + 6x = 180 There a 9x total in the equation equaling 180. Divide 180 by 9 to get 20, which is the measure of the smallest angle. One angle is twice that, which is 40. The biggest angle is 6 times that, which is 120. The three angles are 40º, 20º, and 120º. Hope this helps!
The first mechanic made $2000 for 10 hours. And the second mechanic made $1000 for 5 hours. So therefore if you add how much money they both made, how much moola would they be charged? just say something if you don't understand it.
