Probability: 37.5 %

Step-by-step explanation:

As you can see, there are 3 tiles with the letter B on them out of the 8 tiles there are in the spinner. This can be represented in a fractional form: 3/8, but better yet in a percentage, as expected. Take a look at the following expression in order to convert from a fraction to percentage:

3/8 * 100 - Probability of landing on B in percentage

Now let's solve:

3/8 * 100 =

300/8 =

37.5 % (percent)

37.5%

Step-by-step explanation:

Out of 8 sections, 3 are B

3/8 × 100 = 37.5%

answer is 144

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°
