Step-by-step explanation:
ticket $5.50
popcorn $4
Nine-thousand four-hundred thirty-two
4/10 x 0.04 = (of means multiply)
0.4 x 0.04 =
0.016
If ray EB bisects angle AEC, then m∠AEB=m∠BEC=4x+1.
Angles AEB, BEC and CED together form right angle AED, then
m∠AEB+m∠BEC+m∠CED=90°.
Therefore,
(4x+1)+(4x+1)+3x=90,
11x=90-2,
11x=88,
x=88:11,
x=8°.
Then m∠BEC=4x+1=4·8+1=33°.
Answer: x=8°, m∠BEC=33°.
