Hi! i hope your day is wonderful! my day is going great but could you please help me and make my day even better? i hope theres enough points! you're so kind! thank you!❤

1 p - 6 > -3

add 6 to each side

p>3

for the graph put an open circle on the 3 and make a line that goes to the right

2 n - 4 < 6

ad 4 to each side

n < 10

for the graph put a closed circle ( because it uses this sign ≤) then draw a line going to the left

3 -3 < n +12

subtract each side by 12

-15 < n

draw an open circle on the 12 and draw a line going to the right

4 m - 8 < -2

add 8 to each side

m < 6

draw a closed circle on 6 and draw a line going to the left

5 8 > m - 4

add 4 to each side

12 > m draw an open circle on 12 and a line thats going towards the left

6 n + 11 < 20

subtract 11 from each side

n < 9

draw a closed circle on 9 and a line thats going in towards the left

Step-by-step explanation:

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°
