Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95

Answer: 149
Step-by-step explanation: <EDG = <EDF + <FDG
=86+66= 149
e know that the measure of arc in degrees is equals the measure of the central angle that intercepts the arc.
Now,the measure of arc EFG is given by Arc EFG=central angle EDG= 149
they are supplementary angles
