First you need to make the fractions denominators equal. So you will multiply 1/3 by 4 and 3/4 by 3, leaving you with 4 4/12 - 2 9/12. Simply leaving you with 1 7/12

<h2>Option (c) angle 9 </h2><h2>Option (d) angle 12 </h2>
= x° = ∠9 as they are corresponding angles .
= ∠5 = x° = ∠12 because angle 12 and angle 9 are vertically opposite angles due to which their value is equal . Since angle 5 = angle 9 , x° will also be equal to angle 12 .
