5. (05.06) The coordinate grid shows points A through K. Which points are solutions to the system of inequalities listed below? (2 points)

2x + y is less than or equal to 10
2x - 4y < 8

1. A, C, D, K
2. E, F, G, J
3. A, C, D, H, K
4. E, F, G, H, J

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
