Answer:

solution given:

m<a=m<c

3x+40=x+50

3x-x=50-40

x=10/2=5

now

Answer:

55°

Step-by-step explanation:

<u>It is assumed the angles A and C are congruent:</u>

3x + 40 = x + 50
3x - x = 50 - 40
2x = 10
x = 5

m∠A = 3*5 + 40 = 55°

A commercial aircraft gets the best fuel efficiency if it operates at a minimum altitude of 29,000 feet and a maximum altitude o

natita [175]

Answer:

$x\geq 29,000$ and $x\leq 41,000$

Step-by-step explanation:

Let

x -----> the altitude of a commercial aircraft

we know that

The expression " A minimum altitude of 29,000 feet" is equal to

$x\geq 29,000$

All real numbers greater than or equal to 29,000 ft

The expression " A maximum altitude of 41,000 feet" is equal to

$x\leq 41,000$

All real numbers less than or equal to 41,000 ft

therefore

The compound inequality is equal to

$x\geq 29,000$ and $x\leq 41,000$

All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft

The solution is the interval ------> [29,000,41,000]
