Answer:
The measure of the side is 8.8.
Step-by-step explanation:
Since , then
,
,
and
. From figure we have the following relationship:
(1)
Where is the proportionality ratio.
If we know that , then the measure of side
is:
(1b)
(1c)
The measure of the side is 8.8.
Let's build the equation counting how many x's and 1's are there on each side.
On the left hand side we have 5x's and 8 1's, for a total of
On the left hand side we have 3x's and 10 1's, for a total of
So, the equation we want to solve is
Subtract 3x from both sides:
Subtract 8 from both sides:
Divide both sides by 2:
