A LAMP POST IS 10 FEET TALL AND CAST A SHADOW. THE DISTANCE FROM THE TOP OF THE LAMP POST TO THE TIP OF THE SHADOW IS 20 FEET. FIND THE ANGLE OF THE ELEVATION.
Jeff and his friends is on their way to mount pulag. He drives the car 65 miles due east and then 72 due south .what is the shortest distance he can cover to reach their distinatio.
As soon as possible
A tree cast a shadow that is 10 feet long, the distance from the tip of the tree to the tip of the shadow is 12 ft . What is the height of tree?
sin Angle = 10/20 = .5
as we all know sin 30 degrees = .5

thank you
To find the angle of elevation, we can use trigonometric functions. In this case, we need to use the tangent function since we have the opposite and adjacent sides.
The opposite side is the height of the lamp post, which is 10 feet. The adjacent side is the distance from the top of the lamp post to the tip of the shadow, which is 20 feet.
Let's use the formula: tangent(angle) = opposite/adjacent
Plugging in the values, we have: tangent(angle) = 10/20
Simplifying, we get: tangent(angle) = 1/2
To find the angle, we need to take the inverse tangent (also known as arctangent) of both sides. Using a calculator or a trigonometric table, we can find that:
angle = arctan(1/2) ≈ 26.57 degrees
Therefore, the angle of elevation is approximately 26.57 degrees.
