Question

Solve 1 and 2 plzz tom i have exam plzzzz..

Answer 1

Answer:

Question 1) Given,

a and b form a linear pair.

So, a + b = 180

a = 180 - b (eq.1)

Also given,

(3a - b) = 80 (eq.2)

putting Eq.i in Eq. ii,

3 (180 - b) - b = 80

540 - 3b - b = 80

540 - 4b = 80

540 - 80 = 4b

b = 460/4 = 115

Now, putting value of b in Eq. 1,

a + b = 180

a = 180 - b = 180 - 115 = 65

Therefore,

a = 65 and b = 115

Answer 2

Answer:

Q1 a=65, b=115

Step-by-step explanation:

a+b=180(linear pair)

let it take it as equation 1

3a-b=80

let it take it as equation 2
