Find the value of X first! Then use it to solve the question.
5x + 120 = 360°
X = 48°
Smallest angle = x + 10 = 58°
----------------------------------------------------------------------------------------------------------------------------------
How it works?
What you do is add all the numbers and X's
So 20° + 90° + 10° equals 120° and x + x + x + 2x
equals = 5x + 120° now if you minus 120° from 360° you have 240°.
Now you have to divide 5x by 5 which equals x you also divide 240° by 5 = 48
So X = 48°
