Suppose that you randomly draw two cards, one at a time, without replacement. G1 = first card is green
G2 = second card is green
Draw a tree diagram of the situation.
Find P(G1 AND G2).
Find P(at least one green).
Find P(G2|G1).
Are G2 and G1 independent events? Explain why or why not.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

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°

step-by-step explanation:

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
