10. tan(30) = l / 6√3

l = tan(30) x 6√3

l = 6

cos(30) = 6√3 / y

y = 6√3/cos(30)

y = 12

11. tan(30) = c/30

c = 30 x tan(30)

c = 10√3

cos(30) = 27/w

w = 27/cos(30)

w = 18√3

12.

sin(60) = 36/y

y = 36/sin(60)

y = 24√3

tan(60) = 36/x

x = 36/tan(60)

x = 12√3

olasank [31]

Answer:

Conjecture : 2xy / ( x + y ) ≤ √xy

Step-by-step explanation:

Harmonic mean of x and y = 2xy/( x + y )

<u>Formulate a conjecture about their relative sizes </u>

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture : 2xy / ( x + y ) ≤ √xy

attached below is the proof
