Circle T is shown. Line segments P R and Q S are diameters. Lines are drawn to connect point P and point Q and point S and point R to form 2 triangles. Angle P Q T is 40 degrees. Line P R and Line Q S are diameters of circle T. What is the measure of Arc S R? 50° 80° 100° 120°

(C)100°

Step-by-step explanation:

See attached diagram to understand the problem better.

The measure of arc SR=Central Angle STR

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
