Step-by-step explanation:
sum of all angles in a triangle is 180 degrees
x + 3x + 13 + x - 8 = 180
5x + 5 = 180
5x = 175
x = 37°
A = 3x + 13
3(37) + 13
A = 124°
Answer:
A) 2341 square units
Step-by-step explanation:
Area of a regular polygon= 1/2*perimeter*apothem
Perimeter=22*8=176 units
Apothem=26.6 units
Thus:
A=1/2*176*26.6
A=88*26.6
A=2340.8
So the area of the regular octagon rounded to the nearest square unit is 2341 units^2, aka. Option A
Answer:
0.2 which is 20%
Step-by-step explanation:
divide $5,500 from $1,100. Which equals 0.2 or 20%.
