The situation is represented by a drawing with a right triangle where an airplane is at the top corner, the elevation angle (opposite to the airplane) is 70°, the height (vertical leg) is x, and the adjacent leg (horizontal leg) to the 70° angle is 800.
Then, to find the height x, which is the opposite leg to the angle, you can use the tangent ratio, which is opposite leg divided by adjacent leg:
tan(x) = opposite leg / adjacent leg => tan(70°) = x / 800
Answer: tan(70°) = x / 800
Answer:

Step-by-step explanation:
We want to arrange the following numbers on the number line in order from least to greatest.
The numbers are:

Let us convert everything into decimals to get:

Rearranging from least to greatest, we have:

Let Issac work for x hours, and Ruby works 8 hours more than of Issac, so Ruby work for
hours.
And Svetlana worked four times of Ruby, therefore Svetlana worked for

And total hours they worked together is 136. That is

So Issac worked for 16 hours, Ruby worked for 24 hours and Svetlana worked for 24 times 4 equals 96 hours .
