Having a hard time with this one, see picture.

AM=1 false

BM= ½ true

AM=½ false

BM= √3/2 false

AM= ✓3/2 true

BM=1 false

Step-by-step explanation:

Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= ½ true because BC=1 so BM (half)=0,5=½

AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM= √3/2 false because it's ½

AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2

BM=1 false because BM= ½

yes

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°
