Lines l and m are parallel

soldi70 [24.7K]

Answer:

m∠ABC = 15°

Step-by-step explanation:

<u>Given</u>

m∠ABC = x°
m∠BCD = 25°
m∠CDE = 55°
m∠DEF = 3x°

Add two more parallel lines passing through points C and D.

Consider alternate interior angles formed by the four parallel lines.

<u>The angles between the two middle lines are equal to:</u>

m∠BCD - m∠ABC = m∠CDE - m∠DEF

<u>Substitute values and solve for x:</u>

25 - x = 55 - 3x
3x - x = 55 - 25
2x = 30
x = 15

m∠ABC = 15°

liq [111]

Answer:

8,185,320 different leadership structures

Step-by-step explanation:

Since the order at which the members of the committee are chosen matters, this is a permutation of 4 out 55 people and it is given by:

$n=\frac{55!}{(55-4)!}=55*54*53*52 \\\\n=8,185,320$

8,185,320 different leadership structures are possible.
