1. 2.

3.

4.

For the last one, I think it is 3.07 but I am not confident in my answer. Please help me. Thank you!

If you are trying to solve for x, how can x=3.07? Because -6 + 3.07 = -2.93 ?? you can't have a negative side?

Is it supposed to be a right-angle triangle? And is that left angle bisected?

Sorry, there is a total of 4 questions. The last two look like they were one question so I changed it. Number 1 through 3 I don't have an answer but for 4 I think it was 3.07. Sorry for the confusion.

4.3 / 9.7 =(3x - 8.6) / 1.4 cross multiply 4.3 x 1.4 =9.7(3x - 8.6) 6.02 =29.1x - 83.42 6.02 + 83.42 =29.1x 89.44 = 29.1x divide both sides by 29.1 x =89.44 / 29.1 x =3.0735

Thank you for your help!
