Question

If r || s and M<5 = 128, what’s is M<1??

A. 128
B. 59
C. 62
D. 64

Answer 1

Since lines r and s are parallel and angle 5 is 128 degrees, angle 1, which is a corresponding angle, would also measure 128 degrees. So the correct option is A.

Step-by-step explanation:

If r || s (lines r and s are parallel) and the measure of angle 5 (M<5) is 128 degrees, we need to determine the measure of angle 1 (M<1). In geometry, if two parallel lines are cut by a transversal line, the corresponding angles are equal. Therefore, if angle 5 corresponds to angle 1, then the measure of angle 1 would also be 128 degrees.

Without a diagram, we assume that angle 1 corresponds to angle 5 based on standard conventions. Hence, the correct answer would be: A. 128

Answer 2

We have been given that r is parallel to s. Now, if we look at angle 5 and angle 1, we can see that they are corresponding angles on parallel lines. Corresponding angles are ALWAYS equal, so therefore, your answer is 128 degrees; option A! :)

Hope this helped!
