The height of the tower is 452.66 ft
<h3>What is angle of elevation and depression?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line.
Given:
we have two angles one of which is angle of elevation and another angle depression.
Using trigonometric ratio,
tan ∅ = P / B
tan 32° = h / 425
0.624= h /425
h= 265.569 ft
again,
tan 29° = h(bottom of the tower) / 425
h(bottom of the tower) = 425 × tan 29°
h(bottom of the tower) = 235.581 ft
Thus, Height of tower = h(top of the tower) + h(bottom of the tower)
Height of tower = 265.569 + 235.581
Height of tower = 501.15 ft

Answer:
5. R = 6
6. D = 22
Step-by-step explanation:
5. The area formula is πr2.
If πr2=36π,
π can be canceled out from both sides.
Then, it is r2=36.
If we square root both sides, we get:
r=6 .
Therefore, the radius of your circle is 6.
6.A = 121 π
A = r² π
r² π = 121 π
r = √ 121 = 11
The diameter: d = 2 r = 2 * 11 = 22 units
Answer:
Step-by-step explanation:
Mean = 0.53*23.7% + 0.25*12.7% + 0.22*(-0.112)= 15.71%
standard deviation= sqrt(0.53*(23.7%-15.71%)^2 + 0.25*(12.7%-15.71%)^2 + 0.22*(-0.112-12.40%)^2)= 8.40%
Step-by-step explanation:
Change the division
Sign ➗ to a multiplication ✖ sign the left hand side will remain the same on the lext X will go on top X² - 1 above n then solve...
As I=PRT/100 200×100=Px8x4 so 20000/32=Principal so Principal =625
