what is the answer of this question​

Answer 1

Answer:

$\huge{ \mathbb{ \green{ \underline{ \underline{ANSWER : }}}}}$

3. a + b = 180°

Answer 2

Answer:

It is option 3

Step-by-step explanation:

angle a and angle c are interior alternate angles

• Interior alternate angles equal to each other meaning angle a = angle c ,but do not sum up to 180 degrees

• angle d and angle b are also an another pair of interior alternate angles, hence not equal to 180 degrees

• angle a and angle e are vertically opposite angles meaning they are equal to each other; angle a = angle e

• angle a and angle b are co-interior(conjoined or allied) angles

        co-interior(conjoined or allied) angles are supplementary meaning  

        they sum up to 180 degrees
