Answer:
x = 17
Step-by-step explanation:
We are going to call the missing angle in triangle EDC, "y"
x+y+100=4x+49+y
Eliminate the "y" on both sides
x+100=4x+49
move the x by subtracting the x on the left from the right
100= 3x +49
Move the numbers by subtracting 49 from 100
51 = 3x
Divide both sides by 3
17=x
