Answer:
Both figures are rhombuses, they have the same angle degrees, one is just slanted more and smaller than the other.
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: 11
Step-by-step explanation:
Complementary angles mean both angles sum 90°, then:
(3x + 2)° + 5x° = 90°
3x° + 2° + 5x° = 90°
8x° + 2° = 90°
8x° = 88°
x = 11
Confirmation:
(3x + 2)° 5x°
(3(11) + 2)° 5(11)x°
(33 + 2)° 55x°
35°
35° + 55° = 90°
