A tunnel must be constructed through a mountain. The angle of elevation from one side of the mountain is 38.2°. The angle of elevation from the other side of the mountain is 27.4°. The height of the mountain is 575 m. What is the length of the tunnel through this mountain?

all help will be appreciated!

This is not very clearly written. Here is my interpretation:

A horizontal tunnel must be constructed through a mountain. The angle of elevation from one end of the tunnel to the peak of the mountain is 38.2°. The angle of elevation from the other end of the tunnel to the same peak of the mountain is 27.4°. The height of the mountain above the tunnel is 575 m. What is the length of the tunnel through this mountain?​

If this is correct, then the angles of elevation are base angles of a triangle whose height is given. Does this help you draw a figure and solve for the base length, perhaps using two right triangles?
