You can easily take 8*10, since that equals 80, then add +2. Put parentheses around 8*10+2, then multiply that by 3. You should arrive at your answer
Given that line PN is a perpendcular bisector of line AB, then angles APN and BPN are equal to 90 degrees each.
Also, given that line PN is an angle bisector to angle CPD and angle CPD measures x, then the measure of angle DPN is

.
Thus, the measure of angle DPB = angle BPN - angle DPN

Therefore,
-12.6 as a percent is -1260%
Answer:
<h2>False.</h2>
Step-by-step explanation:
A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.
Therefore, the statement is false.
In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.
An image showing the inscribed circle is attached.
