I might give brainleast depending on the answer

Hi!

So, i know for a fact that 2=30*, because it is the same length.

1 and 3 are the same way, but they are farther out. the answer tp 1 and 3 are not A or D, because that is lower than 90*, which is acute, not obtuse. Now its between B and C. Its not C, because its too far.

So, your answers are

1,3=120*

2=30*

Hope this helps!

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
