Answer


74 AND 106


Explanation

Supplementary angles are those angles that add up to 180.

So, if (2x+4) and (3x+1) are supplementary angles they add up to 180.


(2x+4) + (3x+1) = 180

2x+4+3x+1=180

5x = 180 -5

5x + 175

x = 35


(2x+4) = 2×35 +4

=70+4

= 74

(3x+1) = 3×35 + 1

= 105 +1

= 106
