Mean: 61       Mode: N/A      Median: 70       Range: 75

Step-by-step explanation:

To find the mean, add all of them up and then divide by the number of values (7).

24 + 81 + 70 + 31 + 99 + 87 + 35= 427/7 = 61

Mean = 61

To find the mode, it is the most common number. In this case, no numbers repeat so there is no mode.

To find the median, you organize the set from least to greatest then find the middle number.

24, 31, 35, 70, 81, 87, 99

70 is the middle number.

To find the range, subtract the smallest number from the biggest number.

99 - 24 = 75

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°
