In circle o, su is a diameter. what is m? 100° 108° 130° 160°

answer: 130

step-by-step explanation:

answer:

the measure of the arc st is 130°

step-by-step explanation:

step 1

find the value of x

we know that

∠sor+∠rot+∠tou=180°

substitute the values

(9x+5)°+(13x+15)°+(9x+5)°=180°

solve for x

(31x+25)°=180°

31x=180°-25°

x=155°/31=5°

step 2

find the measure of the arc st

we know that

arc st=∠sor+∠rot > by central angle

substitute the values

arc st=(9x+5)°+(13x+15)°

arc st=(22x+20)°

substitute the value of x

arc st=(22(5)+20)=130°

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
