Answer:
pentagon is a 5 sided polygon with interior angles that add to 540 degrees. Regular pentagons have sides of equal length and interior angles of 108 degrees. The US Department of Defense headquarters is named 'the Pentagon' . ... A hexagon is a 6 sided polygon with interior angles that add to 720 degrees.
Step-by-step explanation:
Answer: 213 meters.
Step-by-step explanation:
A=2(wl+hl+hw) is the formula. l = 6, w = 3.5, h = 9 for this problem.
2([3.5 x 6]+[9 x 6]+[3.5 x 9])
2(21+54+31.5)
2(106.5)
A=213
Sorry if this isn’t a great explanation. Hope this helps.
Answer:
40 degrees
Step-by-step explanation:
Complementary angles have a sum of 90.
y = 90 - x
The angle is 260 degrees less than six times its complement.
y = 6x - 260
90 - x = 6x - 260
350 - x = 6x
350 = 7x
50 = x
This is the measure of the complement.
y = 90 - x
y = 90 - 50
y = 40
This is the measure of the first angle.
