The coordinates of parallelogram abcd are a(0, 0) , b(a, 0) , c(
,
), and d(c, b) .

the coordinates of the midpoint of ac are (
, b2 ).

the coordinates of the midpoint of bd are ( a+c2 ,
).

the midpoints of the diagonals have the same coordinates.

therefore, ac and bd bisect each other.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

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°
