Answer 1

x = 12

Explanation:

Here we go!

What we know:

So 7x and 8x are part of a same side interior angle. meaning, they add up to 180°!

`8x + 7x = 180`

Combine like terms

`15x = 180`

Divide 15 from both sides

`x = 12`

Let's check our work:

plug in x

7(12) + 8(12) = 180

multiply

84 + 96 = 180

add

180 = 180
