Answer 1

Step-by-step explanation:

a) 80°

b) 25°

c) 38°

d)23°

Answer 2

Answer:

a) 80*

b) 25*

c) 38*

d) 23*

Step-by-step explanation:

a) 42*+ 58*+ x = 180 ( Angle Sum Of A Triangle )

  100*+ x = 180

  x = 180-100

  = 80*

b) 115* + 40* + x = 180 ( Angle Sum Property Of A Triangle)

   155*+x = 180

   x = 180-155

   = 25*

c) 90* + 52* + x = 180* ( Angle Sum Property Of A Triangle)

   142* + x = 180*

   x = 180-142

   = 38

d) 125* + 32* + x = 180* ( Angle Sum Property Of A Triangle)

   157* + x = 180*

   x = 180-157

   = 23
