Aim - Create a C++ program to draw an arrow:

• between 2 given coordinates
• arms of length as a given ratio to its body length
• arms at specified incline to the body

Given:

• Start point of arrow as (x1, y1) and end point (x2, y2). Eg: (2, 3) and (10, 100)
• Ratio provided = x : y. Eg 1:10
• Incline of arrow arms (in degrees) = θ. Eg: θ=67

Attempt 1

Attempt 1 relies on individually calculating the slope of all 3 lines and finding points of the arrow by combining equations of distance formula, tangent slope for...
