Answer:
October 10, hope this helps.
Step-by-step explanation:
If Nathan started biking on October 2nd, and he started swimming on October 5th, then since October 10 is the closest day to them that he will be swimming and biking, but also because their both even numbers so he will be biking and swimming on October 10th.
Area of shaded part = (15 - 4) * (14 - 6)
That is the second choice.
Let h represent the height of the building. Then the difference between the two angle measurement locations is
.. h/tan(39°) -h/tan(50°) = 300 ft
.. h = (300 ft)/(1/tan(39°) -1/tan(50°))
.. h ≈ 758 ft
The height of the building is about 758 feet.
Formula used for an equilateral triangle is
Root3 a^2/4
