cos 30 = 7/y

√3/2 = 7/y

y = 7×2/ √3

y= 14/√3

Do you know the answer to this one <br> I need answer plz
Jlenok [28]

The correct option is first option: x=t(y-4f)

Further explanation:

Given equation is:

\frac{x}{t}+4f=y

In order to solve the equation for x, we have to isolate x on one side of the equation

Using Subtraction property of equality

Subtracting 4f from both sides

\frac{x}{t}+4f-4f=y-4f\\\frac{x}{t}=y-4f

Multiplication property of equality

Multiplying both sides by t

\frac{x}{t}*t=t(y-4f)\\x=t(y-4f)

Hence, the correct option is first option: x=t(y-4f)
