Answer:
Step-by-step explanation:
Number of side = n = 7
Sum of interior angles of 'n' sided polygon = (n - 2) *180
= (7 - 2)* 180
= 5 * 180
= 900
x + 150 + x -20 + 140 + 120 + x + 20 + 130 = 900
Combine like terms
x +x +x + 150 - 20 + 140 + 120 + 20 +130 = 900
3x + 540 = 900 {Subtract 540 from both sides}
3x = 900 - 540
3x = 360 {Divide both sides by 3}
x = 360/3
x = 120
Interior angle Exterior angle
∠A = 120 180 - 120 = 60
∠B = 130 180 - 130 = 50
∠C = 120 + 20 = 140 180 - 140 = 40
∠D = 120 180 - 120 = 60
∠E = 140 180 - 140 = 40
∠F = 120 - 20 = 100 180 -100 = 80
∠G = 150 180 - 150 = 30
Answer:
B. 6 + 0.2x
Step-by-step explanation:
- One fifth = 1/5 = 0.2
- One fifth of x = 0.2x
- Sum of 6 and one fifth of x = 6 + 0.2x
I hope this helps!

Answer:
y = (x + 1)²
Step-by-step explanation:
y = 1 + x² + 2x
⇒ x² + 2x + 1 = y
⇒ (x + 1)(x + 1) = y
⇒ (x + 1)² = y
y-intercept when x = 0:
(0 + 1)² = 1² = 1
Therefore, intercepts the y-axis at (0, 1)
x-intercept when y = 0
(x + 1)² = 0
x + 1 = 0
x = -1
Therefore, intercepts (touches) x-axis at (-1, 0)
