No it is not irrational because the sum equals 30.2
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°

Answer:
3.025 (I think)
Step-by-step explanation:
12.5x + 30 = -7.5x + 90.5.
Add 7.5x on both sides
20x + 30 = 90.5
Subtract 30 on both sides
20x= 60.5
divided 20 on both sides
X = 3.025..
