Answer:
1) °
2) °
Step-by-step explanation:
1)
As these two angles are supplementary (They add together to equal 180°) we can setup the equation and solve for x.
2)
Again, these two angles are supplementary we can setup the equation and solve for x

Step-by-step explanation:
a)67.592
b)21.748
c)241.402
The sum of all interior angles in a polygon, regular or not, is
18(n - 2)
where "n" is how many sides are there in the polygon, now, notice, this polygon has 7 sides, so is a heptagon, so the sum of its interior angles will be 18(7 - 2) or 900.
now, subtract all other angles from 900, and what's leftover is "x".
