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

2x + 5y= 18 4x + 20y= -36 Solve and Explain first to get right gets brainliest

Jet001 [13]

because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18

(2x+10y)-(2x+5y)=-18-18

5y=-36

then y=-7.2

because 2x=18-5y

so x=(18-5y)/2=(18-5*(-7.2)）/2=27
