The angle of elevation of the sun from the ground to the top of a tree is 36°.
We are given that:
The sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long.
Now by using the trigonometric identity .
tan θ = P / B
As figure is given below .
AB = Perpendicular = 10 yards
BC = Base = 14 yards
Putting all the values in the trigonometric identity .
tan θ = 10 / 14
θ = 36°
Therefore, the angle of elevation of the sun from the ground to the top of a tree is 36°.

Answer:
yes they both equal 2 1/2
0.27 divided by 0.03 = 9
think of it this way it's like doing it 27 divided by 3 which is = 9
but then u see
9x3=27
9x0.3=2.7
so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.
Answer:
it should be 490 joules
Step-by-step explanation:
9.8m/s^2
10kg * 9.8 * 3m
10kg*9.8*5m
First, we can convert feet to inches 1 foot=12 inches 7 feet=84 inches Next, we find out inches per hour 84 inches/27 1/2 hours ----------- -------------- 27 1/2 27 1/2 =3.054 inches/hour
