Answer:
x = 128.57°
y = 51.43°
Step-by-step explanation:
x = (n - 2) × 180°/n = (7 - 2) × 180°/7 = 900/7° = 128.57°
x + y = 180
y = 180° - 128.57°
y = 51.43°

8 more than twice a number is greater than negative 18. Solve the inequality for the unknown number.
Answer:
x > -13
Step-by-step explanation:
Let x be the number
2x+8 > -18
Subtract 8 from each side
2x+8-8 > -18-8
2x> -26
Divide each side by 2
2x/2 > -26/2
x > -13
Answer:
x > -13
Step-by-step explanation:
Let x be the number
2x+8 > -18
Subtract 8 from each side
2x+8-8 > -18-8
2x> -26
Divide each side by 2
2x/2 > -26/2
x > -13

Since there is no value of x that will ever make this a true statement, the solution to the equation above is “no solution” The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation. and Basically just means for all numbers from minus infinity to infinity. We say real x to distinguish from complex numbers. 0. general ebriety. and Basically just means for all numbers from minus infinity to infinity.

the park is 3 miles long and 2 miles wide. manuel walked around the park two times. how many miles did he walk in all?
(im pretty sure im wrong but is the answer 12?)
Answer:
20 miles.
Step-by-step explanation:
You're on the right track with your answer of 12. You added the sides you knew & multiplied by 2.
I'm picturing the park like a rectangle. So there are two sides that are 3 miles long, and 2 sides that are 2 miles long. For perimeter, we add all the sides.
3 + 3 + 2 + 2 = 10. And he walked the park twice, so 2 x 10 = 20

Given: ∆ABC ≅ ∆DEF. Find DF and m∠B.
Answer:
DF is 3 and angle B is 28
Step-by-step explanation:
If both are congruent, the measurements are the same.
Answer:
DF = 3, Angle B = 28
Step-by-step explanation:
Look how the congruence statement is written. Ac goes with Df and angle E goes with angle B, so they are congruent.
