Answer:

The Correct option is A) 8

The value of a is 8.

Step-by-step 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\times 3a-2\times 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

Choice A is the answer

Why? Because we start with 4, which is denoted a_1 = 4, and because we multiply each previous term by -3 to get the next term (which is what the second row of choice A says).
