Answer 2

Solution➜

To find: The value of a and b .

__________________________

$\huge \: lets \: solve$

$2b + 220 = 360$

$2b = 360 - 220$

$2b = 140$

$b = 70$

We have done so because vertically opposite angles are equal and the total degree of Circle is 360°.

__________________________

$\huge \: lets \: solve \: for \: a$

$\huge a+70+55=180$

$\huge125 + a = 180$

$\huge \: a = 180 - 125$

$\huge \: a = 55$

We have applied interior angle property of triangles.
