Hello, lax600!

The problem is easier than you think ... Note that 45° angle!

The angle of elevation of a flagpole from a point level with its base is 45°.

From a point 20 ft. further away, the angle of elevation is 30°.

What is the height of the flagpole to the nearest 0.1 ft.?Code:A * | * * | * * | * * x | * * | * * | * * | 45° * 30° * * - - - - - - - * - - - - - - - * B x C 20 D
