Please answer the question correctly. I don't understand.
Which sets of side lengths represent Pythagorean triples? Check all that apply.
A. 1, 2, 5
B. 6, 8, 14
C. 8, 15, 17
D. 10, 24, 26
E. 15, 20, 30
F. 28, 45, 53

Some primitive triples are ...  (3, 4, 5)  (5, 12, 13)  (7, 24, 25)  (9, 40, 41)One interesting characteristic of these is that the sum of the last two numbers is the square of the first number.Any multiple of these will be a Pythagorean triple.Now consider your list.  a) (10, 24, 26) = 2×(5, 12, 13) . . . IS a Pythagorean Triple  b) 2×(7, 24, 25) = (14, 48, 50), so (14, 48, 49) is NOT a Pythagorean Triple  c) 3×(3, 4, 5) = (9, 12, 15), so (9, 12, 16) is NOT a Pythagorean Triple  d) (9, 40, 41) . . . IS a Pythagorean Triple  e) 5×(3, 4, 5) = (15, 20, 25) . . . IS a Pythagorean Triple The sets of side lengths that are Pythagorean Triples are ...  (10, 24, 26)  (9, 40, 41)  (15, 20, 25)

the probability that a bird is green (.30) is true

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°
