Question

For a pair of supplementary angle , the magnitude of one is 40° more than that of other. find the two angles​

Answer 1

Step-by-step explanation:

It is difficult to find the value of two angles with only one information about the angles. I can assume that the remaining two angles are equal and thus, following will be the solution.

We know that, sum of all angles of a triangle measure 180° .

∴ Let the two angles be x each.

∴40°+2x°=180°

Subtracting 40 from both sides, we get,

∴2x°=140°

Dividing the equation by 2, we get,

∴x=70°

Hence, if we assume that the angles are the same, both of them will measure 70° each.
