we know that

(x+20)+∠1=180°-------> by supplementary angles

∠1=160°-x

∠1+∠2=180°--------> by supplementary angles

∠2=180-(160-x)-----> ∠2=20+x

∠2=80°------> by corresponding angles

so

20+x=80

x=80-20-------> x=60°

the answer is

60°

we know that

(x+20)+∠1=180°-------> by supplementary angles

∠1=160°-x

∠1+∠2=180°--------> by supplementary angles

∠2=180-(160-x)-----> ∠2=20+x

∠2=80°------> by corresponding angles

so

20+x=80

x=80-20-------> x=60°

the answer is

60°

m = n

Step-by-step explanation:

Two lines (line a and line b) are parallel to each other. If it cut by a traversal line (line l) then, it form four pairs of corresponding angles and each pair of corresponding angles are same (by Corresponding Angle Axiom)

But, in this question the angle m and angle n are the only a pair of corresponding angle and lines are parallel.

Hence we say that the best represents the relationship between angles m and n is m=n

Angle x is 65 degrees.

Step-by-step explanation:

The given angle x plus 25 degrees and the 60 degrees are alternate interior angles. And these angles are congruent.

These angles fall at the opposite sides of transverasl and in between the parallel lines.

So, we can calculate x by making these equal.

degrees

Hence, angle x is 65 degrees.

A

Step-by-step explanation:

Because these angles are alternate interior angles and because alternate interior angles of parallel lines are equal, x = y.
