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,
Answer: 764
Step-by-step explanation:
Answer:
A. 40
Step-by-step explanation:
In such a geometry the measure of the angle is the average of the measures of the intercepted arcs.
∠1 = ∠3 = (50° +30°)/2 = 40°
Answer:
Option C.
Step-by-step explanation:
In this excercise we have to rest the altitude where they hiked on the second place, to the one were they departed from, in order to know how much they hiked.
So we do:
.
The correct option is option C.
X/2 = 68.2
Given that Colin’s number is X, he divided it by 2. Hence it will be x/2 =68.2. Hope this helps! :)
