Question

please answer this question​

Answer 1

Step-by-step explanation:

a+b = 180

a_b= 80

so answer is 130 and 50

Answer 2

Answer:

a = 130

b = 50

Step-by-step explanation:

According to the question, ∠POR and ∠QOR are a linear pair, which means that a + b = 180°  .....  eq.1

Also, the question tells us that a - b = 80° ..... eq.2

So, a + b = 180°

a - b = 80°

Now, making an equation for this, we can write that:

a + b - 100 = a - b

So, solving the equation we get:

a - a + b + b = 100

means that, 2b = 100 or b = 100/2

∴ b = 50

if b = 50, then according to eq.1,

a = 180 - b   →  a = 180 - 50

∴ a = 130

To verify,

according to eq.2)

a - b = 80

130 - 50 = 80

HENCE, VERIFIED
