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
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.
Since the side BC=x therefore the measure of BC is 22 units.
The following formula is used to find the answer.
D = 50 mg (0.6^n)
D is the dosage
n is at any hour
Using this formula and solving the equation for it, the answer is 18.
