Jessica attains a height of 4.7 feet above the launch and landing ramps after 1 second. Her initial velocity is 25 feet per second. To find the angle of her launch, which equation can you use with the given information to solve for θ? (Answer: 1 or 2).

Use the equation you selected to find Jessica's angle, θ. Substitute the known values and solve for θ. What is θ to the nearest tenth of a degree? (Enter only the number.)
