- CPSC 130: Introduction to Computer Programming I Program 3: Decisions In this programming assignment, you will implement two Java programs that deal with decisions. Part1: Determine correct quadrant for angle Complete the program below so that it prompts the user for an angle in degrees, and prints out the quadrant in which the angle is located, represented by Roman numerals, as shown in the following figure. 180⁰ II E III 90⁰ 270⁰ IV Notice that the value of the angle starts at zero degrees at the rightmost point of the circle, moving counterclockwise around the circle as the number of degrees grows. For instance, if the input angle has 100 degrees, it is in quadrant II, while an angle of 300 degrees is in quadrant IV and an angle of 45 degrees is in quadrant I. Each quadrant contains 90 degrees and starts at a multiple of 90. For example, 89 degrees is in quadrant I and 90 degrees is in quadrant II. All the input angle values must be integers between 0 and 359. If the value of an…Evaluate the following expressions, assume the following declarations: int a=28; int b=4; int c=2; int z=0; z*=a/b-c; What is the value of z after expression is evaluated?• FormulaEvaluator.java Requirements: Evaluate the following expression for any value of the variable x, and save the result in a variable of the type double. You must use the abs(), pow(), and sqrt() methods of the Math class to perform the calculation. You may use a single assignment statement with a somewhat large expression, or you may break the expression into multiple assignment statements. The latter may be easier to debug if you are not getting the correct result. 5x +3} ( √8x* — 6x²³ + 4x² + |20x+1) (9x³+7x² +5x+3) Next, determine the number of digits to the left and to the right of the decimal point in the result. [Hint: You can convert the double variable into a String variable using the static method Double.toString(result). Then, on this String variable use the indexOf() method from the String class to find the position of the decimal point (".") and use the length() method to find the length. Knowing the location of the decimal point and the length of the String, you…
