Is it 729 lol why would you put it as mixed number
Answer:
43°.
Step-by-step explanation:
To find the measures of the other two angles, we will need to use various angle properties.
We can use the Supplementary Angles formula to find the adjacent angle to the angle that measures 123°.
180 - 123 = 57°. This is the measure of the first angle.
Now, to find the measure of the second angle, we know that these are vertical angles meaning they are congruent. Therefore, the measure of the angle is 80°.
To find 'x', we will simply need to subtract from 180:
180 - 80 - 57 = 43°.
Answer:
B
When I get questions like this, I just substitute each ordered pair in. In this case, I thought that B didn't seem that it would fit, but I substituted to make sure, and this is what I got:
1-2=9...
...which obviously can't be true, so I knew that B was the correct answer.
Hope I helped! Sorry if I'm wrong. :)

Yes as long as the base is 10
