If cos x = 2 sin x, so the value of sin x cos x is ...

1/2

Step-by-step explanation:

As cosx= 2sinx,

now,

so, sinxcosx = sinx(2sinx) = 2 sin²x

Again,

2sin²x =1

sin²x= 1/2

sinx = 1/ root 2

sinx = sin 30

x = 30

irrational, cannot

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
