Question

In given fig if a-b=
${70}^{o}$
find the value of a,b
​

Answer 1

Answer:

a-b =70° ------(1)

a+b=180° ------(2) [angle made by a straight line]

By Elimination method -

2a=250

a=250/2

a=125

Put 'a' in equation (1)

a-b =70°

125-b = 70°

125= 70+b

b=125-70

b=55°

a=125, b=55

Answer 2

The given attachment will show the step by step method.

a=125

b=55
