Sin30=4/sqrt{3}/x

How to solve?

Step-by-step explanation:

Given that,

...(1)

We need to find the value of x.

We know that,

sin30 = 1/2

Use it in equation (1).

So, the value of x is equal to .

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
