Question

c=57

a=2b

please find a,b,d​

Answer 1

Step-by-step explanation:

$c = a + b \: (Alternate \: Interior \: Angle)$

$57 = a + b$

since, a = 2b

$57 = 2b + b$

$57 = 3b$

b = 57/3

$b = 19$

since, a = 2b

a = 2×19

a = 38

and,

d + b = 180 (co - Interior angles)

d + 19 = 180

d = 180 - 19 = 161
