The angle of elevation of the top of a tower from two points 121 m and 144 m away from the foot of the tower on th same side are

Dennis_Churaev [7]

Answer:

132 m

Step-by-step explanation:

Refer to attachment for figure.

In smaller triangle with angle theta , we have ,

⇒ tanθ = p/b

⇒ tanθ = h/121m

⇒ tanθ = h/121 m

In triangle with angle 90-∅

⇒ tan(90-θ) = p/b

⇒ cot θ = h/144 m

Multiplying these two ,

=> tanθ . cotθ = h/121 m × h/144m

=> 1 = h²/ (121 m × 144m )

=> h² = 121m × 144m

=> h= √ ( 121m × 144m)

=> h = 11m × 12m

=> h = 132 m

What is the distance?(-4,2) (-2,-2)

It is 2x and 4y, so you need to use pythagorean theorem. 2 squared is 4, and 4 squared is 16. Add them, and you get 20. The problem is that that won't square to a whole number, so the closest I can get it is the square root of 20, or 2 root 4.

Using the numbers 8, 6, 4 write an expression that equals 7

8090 [49]

$\dfrac{8-4}{4}+6=\dfrac{4}{4}+6=1+6=7$

$8-\dfrac{8-6}{6-4}=8-\dfrac{2}{2}=8-1=7$

$\dfrac{8+6}{6-4}=\dfrac{14}{2}=7$
