The rocket's launch angle is 75.42 degrees.
To estimate the launch angle, we need to find the angle between the vertical line and the diagonal trajectory line.
You can use a protractor or trigonometric functions to measure this angle.
Trigonometric approach:
We have the triangle ABC, where AB is the horizontal distance (13 ft), BC is the vertical climb (50 ft), and we need to find the angle ACB (launch angle).
tan(ACB) = BC / AB = 50 ft / 13 ft
take the inverse of the tangent value
= 75.42 degrees
