Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleelevation) = treeheight / shadowlength. 1. using simple algebra, rearrange that equation to solve for treeheight. (note: don't forget tangent). 2. complete the below code to compute treeheight. for tangent, use the tan() function, described in the "math functions" link above.

Write an application that allows a user to enter the names and birthdates of up to 10 friends. continue to prompt the user for names and birthdates until the user enters the sentinel value “zzz” for a name or has entered 10 names, whichever comes first. when the user is finished entering names, produce a count of how many names were entered, and then display the names. in a loop, continuously ask the user to type one of the names and display the corresponding birthdate or an error message if the name has not been previously entered. the loop continues until the user enters “zzz” for a name. save the application as birthdayreminder.java.

In this lab, you complete a python program that calculates an employee's annual bonus. input is an employee's first name, last name, salary, and numeric performance rating. if the rating is 1, 2, or 3, the bonus rate used is .25, .15, or .1 respectively. if the rating is 4 or higher, the rate is 0. the employee bonus is calculated by multiplying the bonus rate by the annual salary.
