Area of AAFD= 54centimeters squared
Answer:

Step-by-step explanation:
We are given that
Measure of intercepted arc are

We have to find the measure of angle 3.
We know that
Internal angle=half the sum of measures of its intercepted arc.
Using this property
Measure of angle 4=
Measure of angle 4 +measure pf angle 3=180 degrees (linear pair)
Substitute the values then we get


Hence, the 
Answer:
Zero slope
