ans the both question plzz​

Answer 1

Step-by-step explanation:

(a) Sum of angle of pentagon =540

x+x+x+x+x=540

5x=540

x=108

(b) 90+x=180 (linear pair)

x=180-90=90

30+z=180 (L. P.)

z=180-30=150

Sum of interior angle of triangle =180

90+30+angle1=180

120+angle1=180

angle1=180-120=60

60+y=180 (L. P.)

y=180-60=120
