With math my parents will kill me if i dont get a's i will mark brainleast rate a 5 and just !

Question 3: Line 3

Question 4: 7

Question 5: -21

Step-by-step explanation:

Line 3 shows the answer because instead of adding 25 on the right which is what they should've, they subtracted 25

You need to distribute in the 2nd step so you get 4x-12=16 which simplifys to 4x=28 and 28/4 = 7

You can put it into an equation then solve:

=4+(-11)

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°
