Question

6. In the given figure, 21 and 22 are supplementary
angles
Il 21 is decreased, what changes should take place
in 22 so that both the angles still remain
supplementary
​

Answer 1

Answer:Angle 22 should increase.

Step-by-step explanation:

Angle 21 and 22 are supplementry.

Lets suppose angle 21 to be 'x' and 22 to be 'y'.

So, x+y=180°

Suppose x is decreased by n degrees,

(x-n) + (y) = 180-n

So n degrees should be added to y (angle 22).
