25 degrees is the answer. CBE is supplementary to ABC. That means those two angles add up to 180 degrees.
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
Answer:
x=7
Step-by-step explanation:
2 3/4 because if you do the math good you get this
