Find thevalue of unfnown angles

x=55; 65+60+x=180

z=75; 105+z=180

y=50; 55+75+y=180

Step-by-step explanation:

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
