Question

substitute the given values into the given formula and solve for the unknown variable. if necessary, round to one decimal place.

p = a + b + c; p = 33, a = 9, b = 8 (perimeter of a triangle)

Explanation:

Step1: Substitute given values

Substitute $P = 33$, $a = 9$, and $b = 8$ into $P=a + b + c$. We get $33=9 + 8 + c$.

Step2: Simplify the right - hand side

First, calculate $9 + 8=17$. So the equation becomes $33 = 17 + c$.

Step3: Solve for $c$

Subtract 17 from both sides of the equation: $c=33 - 17$.
$c = 16$.

Answer:

$16$
