Question

if a and b form a linear pair if a-b =80then values of a and b respectively are ​

Answer 1

Answer:

a = 130 and b = 50

Explanation:

a+b = 180........eq 1

a-b = 80..........eq 2

$a = 180-b$

Now subsitute this in Eq 2

$a-b=80\\\\\\180-b-b=80\\\\\\180-2b=80\\\\\\180-80=2b\\\\\\100=2b\\\\\\\frac{100}{2}=b\\\\\\50 = b$

Now subsitute this value in Eq 1

$a+b=180\\\\\\a+50=180\\\\\\a=180-50\\\\\\a=130$
