Question

Help with supplementary geometry?

When I use the formula, I end up with a decimal, did I do something wrong?

Example:

8x+14

and

9x.

so, 8x+14 + 9x= 180.

When I combine like terms, I get decimals and end up getting the question wrong?

17x+14 = 180
-14 -14 =
17x = 166

When I divide it, I get 9.7?

I really need help on this, it's really frustrating.

Answer 1

What do you need help with?

Answer 2

I edited my post.

Answer 3

We need to see the original problem. Perhaps it is not the sum that is equal to 180.

Answer 4

Well, that was an example, here is the problem.

Answer 5

Yes. Add the two angles and the sum will be 180.

Answer 6

I do this yet I get the wrong answer, I follow the procedure to do this problem. But, in the end, the answer doesn't reflect. The question to that problem is to solve for X.

Answer 7

15x-20+35x=180
50x-20=180
50x=200
x=4

Answer 8

Sorry, wrong equation, I just realized that

Answer 9

here is the real problem.

Answer 10

Alternate exterior angles are equal.

Answer 11

I know that, just how do I solve for x though?

Answer 12

Write the equation and post it. Then I will help you with it.

Answer 13

The equation is:

8x + 14 + 9x = 180

Answer 14

I thought we said that the two exterior angles are equal?
