Answer 1

The Correct option is A) 8

The value of a is 8.

Explanation:

Vertical Angles:

The angles opposite each other when two lines cross.

They are always equal.

∠ 2(3a-7)° and ∠ (5a-6)° are vertical angles.Hence are equal.

So on Substituting we get

`2(3a-7)\°=(5a-6)\°`

Applying distributive property we get

`2* 3a-2* 7=5a-6\\6a-14=5a-6\\6a-5a=14-6\\\\\therefore a=8`

The value of a is 8

The Correct option is A) 8
