a = 90°
b = 90°
c = 42°
d = 48°
e = 132°
Explanation:
Here as you can see c and 132° is vertically opposite to each other so it can be name as vertically opposite angle....
- Vertically opposite angle are always equal to each other....
e = 132°
Now....
here c and d are supplementary angle...
c + d = 180°
132° + d = 180°
d = 180° - 132°
d = 48°
Now...
b = 90° ( being vertically opposite angle )
Here a and b are supplementary angle ....
a + b = 180°
a = 180° - 90°
a = 90°
Now...
c + 138° = 180° ( supplementary angle )
c = 180° - 138°
c = 42°..
