The Koch snowflake is a fractal shape. At level 0, the shape is an equilateral triangle. At level 1, each line segment is split into four equal parts, producing an equilateral bump in the middle of each segment. Figure 7-15 shows these shapes at levels 0, 1, and 2.   Figure 7-15 First three levels of a Koch snowflake At the top level, the script uses a function drawFractalLine to draw three fractal lines. Each line is specified by a given distance, direction (angle), and level: The initial angles are 0, -120, and 120 degrees. The initial distance can be any size, such as 200 pixels. If the level is 0, then t Python GUI TestIncomplete Program generates the correct image

Add formulas to complete the table of hours used. In cell B17, create a nested formula with the IF and SUM functions that check if the total number of hours worked in week 1 (cells B9:F9) is equal to 0. If it is, the cell should display nothing (indicated with two quote marks: ""). Otherwise, the cell should display the total number of hours worked in week 1. Copy the formula from cell B17 to fill the range B18:B20
