from a point at the waters edge, a bridge arch 58 metres away has an angle of elevation of 5 degrees, and the top of a yacht mast 14 metres away has an angle of elevation of 12 degrees. what is the...

there is a x and y graph and they want you to put an arrow and a circle showing where the degree is.

An arborist wants to prune an oak tree that has grown too tall. The arborist takes a 15-foot ladder and places it on a horizontal surface on the ground so it leans against the tallest part of the...

I've tried to solve the math problem. When I draw the diagram, it looks like I have to use the Cosine. However, I don't have an angle degree. I think I've missed a step somewhere. Wouldn't I have...

Solve for tan 21 and sin 66

in an experiment of determining to gravity is showing of 18 degree in the vertical plane is given to a simple pendulum of length 10 cm how much distance is required for the pendulum to freely.

A heavy ball with a radius of 2.9 cm is dropped into the container. As a result the height of the water increases to h cm as shown. Find the value of h

sec^2(x)/1-cos2x=csc^2(x)/1+cos2x

1-2sin^2(x)/sec^2(x)=cos2xcos^2(x)

If sin theta=-0.53, find cos(pi/2-theta)

tan theta=-4/3 Find tan (theta/2)
