Question

Pls answer the question with explanation pls
find the value of abc​

Answer 1

Answer:

c=50°

b=130°

a=20°

in triangle ADC,sum of interior angle 180°

BDC complementary ngle sum should be 180°

in triangle ABD ,sum of interior angles 180°

Answer 2

Answer :

60° + 70° + c = 180° (Angle sum property of triangle)

130° + c = 180°

c = 180° - 130°

c = 50°

b + c = 180° (Linear Pair)

b + 50° = 180°

b = 180° - 50°

b = 180° - 50°

b = 130°

30° + a + b = 180° (Angle sum property of triangle)

30° + a + 130° = 180°

160° + a = 180°

a = 180° - 160°

a = 20°
