In the right triangle shown B=60 and AB=4V3 how long is BC plz help

x = 2√3.

Step-by-step explanation:

We know the measure of angle B and the length of the hypotenuse so we need to use the cosine function (cos = adjacent/hypotenuse).

cos 60 = x / 4√3

x = 4√3 * cos 60

x = 4√3 * 1/2

x = 2√3.

answer4 to the second power is 16

and 4 to the third power is 64,

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
