Answer 1

Answer:

180° is the correct answer I think

Answer 2

Angle P,Q,R,S,T=36 degree

Step-by-step explanation:

The sum of internal angles of a Pentagon=540

Therefore, one internal angle=108 degree

The sum of external angles of a Polygon is always 360 degrees

Hence,one external angle will be 72 degree

Consider the Triangles:

The sum of its angles will always be 180 degrees

Hence, 72+72+___ =180

ie, 180-(72+72)= Third angle (angle P,q, and so.on)

180-144=36

And hence, the angles P,Q,R,S,T =36 degree

Sum=36+36+36+36+36

=180
