Answer:
If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°.
Step-by-step explanation:
Where S is the angle-sum, and n is the number of sides. (2n-4) x 90 where n is the number of sides.

Step-by-step explanation:
Answer:
q=8/5 r
Step-by-step explanation:
Step 1: add -3q to both sides
-7q+12r+-3q=3q-4r+-33
-10q+12r=4r
Step 2: Add -12r to both sides
-10q+12r+-12r=-4r+-12r
-10q=-16r
Step 3: Divide both sides by -10.
-10q/-10=-16r/-10
q=8/5r
