The radius of a Ferris Wheel is 30 feet. The angle between each position is 40 degrees. Point A is located 42 feet above the ground. Find the height of the Ferris Wheel at point B. Correctly round your answer to 3 decimal places. Do not include the units.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
