Question

Please help me (geometry)

Answer 1

Answer:

x = 7

Step-by-step explanation:

When two parallel lines are cut by a transversal, the corresponding angles are equal.

8x +2 = 7x + 9

Subtract 2 from both sides

8x = 7x + 9 - 2

8x = 7x + 7

Subtract 7x from both sides

8x - 7x = 7

x = 7

Answer 2

Answer:

x=7

Step-by-step explanation:

The 2 given angles are vertical to each other, so that means they are equal to each other.

To solve, set up an equation:

$7x+9=8x+2$

Solve by isolating the variable. [Subtract and divide]

$7x=8x-7$

$-x=-7$

Multiply both sides by -1 to get rid of the negative sign.

$x=7$

I hope this helps!
