How is this solved?
Hi there! Struggling a bit with solving this. I would think the answer could be solved like so:
5.00 X 9.8 = 49
49 X 40.00 = 1960
but 1960 is incorrect, what am I missing here?
Thanks!
The line from a point 150 feet from the base of a redwood tree to the top of the tree is 211 feet. If the angle of elevation to the top of the tree is
54.6 degrees, find the height of the tree in trigonometric form.
a) 0211 sin(54.6) [ft.]
b) O150 sin(54.6) [ft.]
c) 0211 tan(54.6) [ft.]
d) O150 cos(54.6) [ft.]
e) ONone of the above

- A student wanted to calculate the radius, r, of the base of a spherical cylinder. The student measured both the volume of the cylinder and its height and obtained the following: Volume, V = (92± 1) cm^3 . Height, h = (11.5 ± 0.1) cm. V = π * (r^2) * h. Calculate the radius of the base of the cylinder.arrow_forwardA park ranger wanted to measure the height of a small tree. The ranger stood 10.50 meters from the base of the tree.
