Final answer:
To solve for x in the ratio AC:BC = 7:4, set up a proportion and solve for the missing term.
Step-by-step explanation:
To solve for x in the ratio AC:BC = 7:4, we need to find the value of the missing term. We can set up a proportion using the given ratio:
AC/BC = 7/4
Cross multiplying, we get:
AC * 4 = BC * 7
Divide both sides by 4 to find the value of AC:
AC = (BC * 7) / 4
Now, substitute the value of AC into the equation to solve for x.
