an airplane lands at an airport 80 miles west and 30 miles north of where it took off. How far apart are the airports.
MArishka [77]

Answer:

85.44 miles apart

Step-by-step explanation:

According to the question;

  • The airplane flew 80 miles west and 30 miles north

We are supposed to determine how far apart are the airports.

  • The shortest distance will be the displacement from the initial point.
  • We are going to use the Pythagoras theorem;
  • a² + b² = c² , where a and b are the legs of a right angled triangle and c is the hypotenuse.
  • Therefore, in this case; our legs will be 30 miles and 80 miles, so we need to determine the hypotenuse;

That is;

c² = 80² + 30²

    = 6400 + 900

    = 7300

c = √7300

  = 85.44

Thus, the airports are 85.44 miles apart

What is the length of BC¯¯¯¯¯ ? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vertex A lies above
OlgaM077 [116]

Answer: The length of BC is 22 units.

Explanation:

It is given that the Triangle ABC with horizontal side BC. Vertex A lies above side BC. Angle B and angle C are marked congruent. The length of side AC is labeled as 2x-24. The length of side AB is labeled as x-2. The length of side B C is labeled as x.

If two angles of a triangle are same it means the triangle is an isosceles triangle.

Since the angle B and C are congruent therefore the lines AB and AC are same.

2x-24=x-2

2x-x=-2+24

x=22

Since the side BC=x therefore the measure of BC is 22 units.
