length of other diagonal is 17 feet.
we have given,
length of rectangular window = 15 feet
width of rectangular window = 8 feet
diagonal length = 17 feet
we can also apply pythagoras theorem to check if it is a diagonal of rectangle or not
i.e 17² = 15² + 8²
or 289 = 225 + 64
or 289 = 289
hence given diagonal length is the diagonal length of rectangular window.
diagonals joining opposite vertex of rectangle are equal.
.since the length of one diagonal is 17 feet.
therefore length of other diagonal will be 17 feet as well.
after 10 years the salaries are the same.
in order to solve the problem, we must first use the information given to set up two different equations - one for company a and one for company b. company a has a starting salary of $24,000 plus a yearly increase of $3,000 also written as: $3000x + $24,000.
company b has a starting salary of $30,000 plus a yearly increase of $2,400 also written as $2400x + $30,000.
since we want to find out how long it will be before the salaries are equal, we can set the two equations equal to each other and solve for 'x' = the number of years:
3000x + 24000 = 2400x + 30000
combine like terms: 600x = 6000
solve for x: x = 10 years
