Question

Solve for x???????????

Answer 1

Answer:

$x=9$

Step-by-step explanation:

For this you just have to make an equation and in order to do that you have to know that all these angles will equal 180°. Now we can write it out.

$3x-4+13x+2+5x-7=180$

Now we combine like terms:

$21x-9=180$

Add the 9 on both sides:

$21x=189$

Divide the 21 on both sides:

$x=9$
