Question

find the values of a b c​
Give reasons also

Answer 1

Answer:

a = 63°

b = 80°

c = 37°

Step-by-step explanation:

C + 143° = 180° [ Linear Pair ]

C = 180°- 143°

C = 37°

b = 80° [ corresponding angles]

a + b + c = 180° [ sum of angles of a traingle = 180°]

a + 80° + 37° = 180°

a = 180° - 117°

a = 63°

Answer 2

sum of interer angle of atriangle is 180

so,a=48

c +143= 180 (linear pair)

so,c=37

now from upper triangle

a+b+c=180

48+b+37 = 180

b=95
