Pls help lol its a quiz

Letter F

Step-by-step explanation:

The sum of the 3 interior angles of a triangle would add up to 180 degrees. So the 42 plus the other 42 is 84. Something plus 84 would equal that 180 degrees.

Hope this makes sense and helps you! :)

(P.S, I hate quizzes.)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

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°
