We will use the angle bisector theorem here for 
. ED being the angle bisector.
Thus, from the diagram we will have:
We will now plug in the values given in the diagram.
Answer:
15/60
First divide by 3 to each
5/20
Now divide by 5 to each
1/4
6/10 = 3/5
Simply divide the numerator and denominator of 6/10 by 2. 6/10 is the same as 3/5.
Answer:
90 degrees
Step-by-step explanation:
If two angles are supplementary they are a linear pair which means they form a straight line, and if you know a straight line equals 180 degrees which is the total degrees of a triangle.
Now if you have two supplementary angles and they are congruent that means not only are they right angles but its half of 180 so you divide these pair of 2 by 180 giving you your total of 90 degrees.
