Question

If angles “a” and “b” form a linear pair of angles and “a-2b=30”. Find the

value of “a” and “b”.​

Answer 1

Answer:

a = 130° b = 50°

Step-by-step explanation:

given a and b are linear pair

so,

a + b = 180° ......eq1

also given a - 2b = 30 ...eq2

solving both equations

we get

subtract 2 from 1

(a - 2b) - (a + b) = 30 - 180

》-3b = -150

》b = 50°

now a + b = 180

so

》a + 50 = 180

》a = 180 - 50

》a = 130°
