Identify two statements that contradict each other. I. ∠M is an obtuse angle.
II. m∠M + m∠P = 90°
III. 180° − m∠M = 25°
IV. m∠P = 120°

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

60 for the first and 130 for the second
