The sum of 4 numbers is 771. the ratio of the first to second number is 2: 3. the ratio of the second to third is 5: 4. the ratio of the third to the fourth is 5: 6. find the value of the second number

answer:

let the 1st number = x

x + 3x/2 + 3x/2 * 4/5 + 6x/5 * 6/5

x + 3x/2 + 6x/5 + 36x/25 = 771

50x+75x+60x+72x=38550 multiply each side by 50.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

multiply each one by 3.14
