Answer:
The length of the third side of the triangle is 
Step-by-step explanation:
Let
c ----> the length of the third side of the triangle
we know that
Applying the law of cosines

we have

substitute the given values



The measure of ∠ACB will be 110°
<u><em>Explanation</em></u>
According to the diagram below,
and
are the perpendicular bisectors of
and
respectively and they intersect side
at points
and
respectively.
So,
and 
Now, <u>according to the
postulate</u>, ΔAPE and ΔCPE are congruent each other. Also, ΔCFQ and ΔBFQ are congruent to each other.
That means, ∠PCE = ∠PAE and ∠FCQ = ∠FBQ
As ∠CPQ = 78° , so ∠PCE + ∠PAE = 78° or, ∠PCE =
° and as ∠CQP = 62° , so ∠FCQ + ∠FBQ = 62° or, ∠FCQ =
°
Now, in triangle CPQ, ∠PCQ = 180°-(78° + 62°) = 180° - 140° = 40°
Thus, ∠ACB = ∠PCE + ∠PCQ + ∠FCQ = 39° + 40° + 31° = 110°
3x-2 = x + 5
sum means +
2 less means -2
product of 3 and x means 3x
