Answer:
x = 38
∠P = 26º
Step-by-step explanation:
The sum of the angle in a triangle is 180
x + (x + 78) + (x - 12) = 180
Combine like terms
3x + 66 = 180
Subtract 66 from both sides
3x = 114
Divide both sides by 3
x = 38
-----------------------
∠P = x - 12
∠P = 38 - 12
∠P = 26º
Answer: Angle bisector
The angle bisector is the line that cuts an angle in half. The three angle bisectors all intersect at the same point which is the incenter. The incenter is the center of the circle in which is largest possible, yet it's fully inside the triangle. No part of this circle is outside the triangle.
Answer:

is equivalent to
.
This is because 
The rule is, in order to add fractions, your denominators must be equivalent. In other words, you must have the same denominator for both fractions.
<em>Now what do we do? We add!</em>

This is because 4 + 1 = 5.
Your answer is
.
I hope this helps!
