Answer:
6 1/3
Step-by-step explanation:
8 1/2 - 2 1/6
you need to get a common denominator of 6
1/2 * 3/3 = 3/6
8 3/6
-2 1/6
-----------
6 2/6
we can simplify 2/6 by dividing top and bottom by 2
6 2/6 = 6 1/3
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
Sqrt ( (-4)^2 + (-sqrt2i)^2 )
= sqrt (16 + 2)
= sqrt 18
= sqrt9 * sqrt 2
= 3 sqrt2 (answer)
