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°.

Answer:
26 mm
Step-by-step explanation:
A=wl= 42 mm²
l=7, w= 42/7= 6 mm
P=2(l+w)= 2(7+6)= 26 mm
Put them in order from lowest to highest. Identify the lowest number in the data set, as well as the highest number. Subtract the lowest number in the set from the highest number. The resulting value is the range of the set of temperature values.
