Answer 2

$\huge\mathtt\pink{A}\mathtt\red{N}\mathtt\blue{S}\mathtt\green{W}\mathtt\purple{E}\mathtt\green{R}\: 128°$

Step-by-step explanation:

On line AOD: Three angles are given. And value of angle of line is 180°

Hence:-

$\large \: \frac{x}{2} + 5 (\frac{x}{2} - 1) + x + 9 = 180$

$\large \: 6( \frac{x}{2}) - 5 + x + 9 = 180$

$4x + 4 = 180$

$\large \: x = 43$

Now in triangle containing angle a and b The third angle is vertically opposite to one of angle present on AOD

Hence:-

Third angle = 43+9=52

Now a+b+52=180. ( Triangle sum property)

a+b=128°
