Angle b = 120
x+25+2x+50 = 180
3x+75= 180
3x= 105
X= 35
Because angle in above, x is 35, we can plus it in to find the value. The angle equals
35+25
Angle ABY = 60.
Angle B is supplementary to that angle so it would equal 120 degrees
180-60= 120.
Angle E is congruent to B therefore it would also be 120 degrees.
