Answer:
Angle E = 73 degrees
Step-by-step explanation:
Supplementary means it equals 180 degrees.
So to find x, you add the 2 equations.
2x + 15 + 5x - 38 = 180
which equals 7x + (-23) = 180 = 7x - 23 = 180
7x = 203 You move the -23 to the other side
203/7 = 29 So x = 29 degrees
So to find angle E, you put in 29 degrees for x.
2 x 29 + 15 = 73 degrees
