The answer is -7. The work is in the picture.
Answer:
A. 39°
Step-by-step explanation:
Complementary angles total 90°. The angle of interest is ...
90° -51° = 39°
Angle 2 and 7 are alternate exterior angles, which are congruent...so angle 7 is also 47 degrees.
Angles 7 and 5 form a straight line (which = 180 degrees), so subtract the measure of angle 7 from 180 to find the measure of angle 5.
Angle 5 = 180-47=133 degrees
Answer:
The same line
Step-by-step explanation:
Recall that if two graphs, representing a system of equations has infinite solutions, this means that point on one graph must coincide with a corresponding point on the other graph. The only way that this can happen is if both graphs coincide with each other perfectly, which is to say that they are the same line.
