When an angle is reflected across a line, what happens to its measure? A It remains the same

B It doubles

C It halves

D Not enough information

i think the answer is c sorry if it's wrong

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

the graph is negative for all real values of x where   -6 < x < -2.

step-by-step explanation:

this refers to the values of f(x) in the area below the x-axis.
