Let the distance of Jill form the base of the tower be x, then tan 40 = 100/x
x = 100/tan 40 = 100/0.8391 = 119.18 meters

Let the height of the tower from the level of the top of Jill's apartment be y, then tan 30 = y/119.18
y = 119.18 x tan 30 = 68.8 meters

Therefore, the height of Jill's apartment is 100 - 68.8 = 31.2 meters

How many triangles can be constructed with sides measuring 6 cm, 2 cm, and 7 cm? more than one none one

serious [3.7K]

Answer:

None

Step-by-step explanation:

By using the equation a^2 +b^2=c^2 we can see if it will work.

Substitute a for 6 and b for 2 to get 6^2+2^2=40

when you $\sqrt{40}$ you don't get 7 therefore you cant make any triangles
