1 ) - 6.5 r = - 58.5
2 ) c - 5.5 = 2.3
3 ) 56 = - 5.6 s
4.)d/4=4.7
5 ) - 9 = 6.9 + x
6 ) 23.5 = 4.7 z
7 ) - 2.7 = v + 4.9
8 ) 2.6 =k/3
9 ) - 5.6 f = 44.8

Answer and Step-by-step explanation:

1) - 6.5 r = - 58.5

- r = - 58.5/6.5

- r = - 9

2) c - 5.5 = 2.3

c = 2.3 + 5.5

3) 56 = - 5.6s

56/5.6 = - s

10 = - s

- 10 = s

4) d/4 = 4.7

d = 4.7 / 1/4

d = 4.7 * 4

5) - 9 = 6.9 + x

- 9 - 6.9 = x

- 15.9 = x

6) 23.5 = 4.7z

23.5/4.7 = z

5 = z

7) - 2.7 = v + 4.9

- 2.7 - 4.9 = v

- 7.6 = v

8) 2.6 = k/3

k/3 = 2.6

k = 2.6 / 1/3

k = 2.6 * 3

9) - 5.6f = 44.8

- f = 44.8/5.6

- f = 8

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°
