Answer:
m=4
Step-by-step explanation:
add 10 to both sides m-10+10=-6+10
m=4
Simplify 2r + 10 + 4r to 6r + 10
Expand it
Simplify 6r + 18 - 4 to 6r + 14
Cancel 6r on both sides
Since 14 = 10 is false, there is NO solution for this equation so no answer.
Angle DFB = (1/2)*[(arc CE)+(arc BD)]
Angle DFB = (1/2)*(84+38)
Angle DFB = (1/2)*122
Angle DFB = 61
(Angle DFB) + (angle DFE) = 180
angle DFE = 180 - (Angle DFB)
angle DFE = 180 - 61
angle DFE = 119 degrees
