Question

one of angle is 116 what is next one​

Answer 1

Answer:

Let the two angles be A,B

Given

sum of two angles is 116⟹A+B=116⋯(1)Difference between the angles is 21⟹A−B=21⋯(2)(1)+(2)⟹2A=137⟹A= 2137 =68.5⟹B=116−A=116−68.5=47.i5Sum of angles in a triangle is 180Third angle is 180−(A+B)=180−116=64Measure of each angle is 68.5,57.5,64

Answer 2

If you are talking about Straight Angle or Angles of Linear Pair then :-

2nd angle = 180° - 116°

= 64°
