Answer:
Step-by-step explanation:
Here ABCDE is a pentagon and each interior angles A,B,C,D,E=108
Consider quadrilateral ABQE
Sum of angles in Quadrilateral =360
108+108+108+Q=360
Q=36
Similarly all P=Q=R=S=T=36
P+Q+R+S+T=180

∠P + ∠Q + ∠R + ∠S + ∠T = 180°
Step-by-step explanation:
In question figure,
To find, ∠P + ∠Q + ∠R + ∠S + ∠T = 180°
We know that,
The pentagon of each interior angle = 108°
∴ ABCDE is a pentagon,
∠ A, ∠B, ∠C, ∠D and ∠E = 108 °
Consider quadrilateral ABQE ,
The sum of all angles in quadrilateral = 360 °
∴ ∠ A + ∠B + ∠C + ∠Q = 360 °
⇒ 108° + 108° + 108° + ∠Q = 360 °
⇒ ∠Q =360 °- 324° = 36°
Similarly.
All ∠P = ∠Q = ∠R = ∠S= ∠T = 36 °
∴ ∠P + ∠Q + ∠R + ∠S + ∠T = 180°
