Answer:
55°
Step-by-step explanation:
A couple of auxiliary lines can be helpful.
We see that 45° is an exterior angle to the bottom triangle, which has remote interior angles that must total 45°. This means the interior angle at bottom left must be 45° -15° = 30°.
The upper right interior angle is alternate to that, so is the same measure. The exterior angle x to the upper triangle is then the sum of the remote interior angles:
x = 25° +30°
x = 55°
55 because as u can see in the opposite side it’s 55 and the z is in the other side but the same amount of degrees
Answer:
A.26
B.116
C.64
Step-by-step explanation:
the answer is D, because the “ a “ thats alone has an invisible one in front of it, so it’ll be 1a+2a+3a+4a
Answer:
They can`t cross because the slopes are the same.
Since the first equation isn`t simplified, I`ll simplify it.
-x + 4y = -8
4y = x - 8
<u>y = x - 2</u>
After both are simplified, both slopes will be positive 1x. That means the lines are parallel and never cross. I`m sorry if this wasn`t much help, but that is the only answer I can think of. If there is not other option than placing a real answer, than I wouldn`t know how to solve this, sorry.
