Answer:
Sachet town is 12km from the airport
Step-by-step explanation:
In this question, we are asked to calculate the distance from sachet town to the airport.
This can be calculated by referring to a diagrammatic representation. Please check attached file.
Let’s proceed with the calculations however.
From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.
Mathematically;
x^2 + 16^2 = 20^2
x^2 = 20^2 - 16^2
x^2 = 400 - 256
x^2 = 144
x = sq.rt of 144
x = 12km
Standard form.
Where m is the slope and n is the point where x=0. Then, you have,
To obtain n use the point they give you,
So n=-7 and then
