Answer 1

Answer:

Step-by-step explanation:

a)

x+70 = 180[starightline]

x = 110

y+60 = 180[straight line]

y = 120

z+70 = 180

z = 110

a+80 = 180

a = 100

Angle sum of a pentagon = 540

a+b+x+y+z = 540

b = 540 - 100 - 110 - 120 - 110

b = 540 - 220 - 220

  = 540 - 440

b = 100

c + b = 180[straight line]

c = 80

b)

z+150 = 180

z = 30

x+100 = 180

x = 80

y+140 = 180

y = 40

t+145 = 180

t = 35

150 + 100 + 140 + t + q = 540 [Angle sum property of pentagon]

q = 540 - 135 - 290

  = 115

q + r = 180

r = 180 - 115

r = 65
