The hypotenuse in a right triangle is 13 cm. of the other two sides one is 7 cm longer than the other determine the lengths of those two sides

Assuming x represents the length of the first side.

Use pythagorean theorem to solve:

a^2 + b^2 = c^2

x^2 + (x+7)^2 = 13^2

x^2 + x^2+14x+49 = 169

2x^2 + 14x - 120 = 0

Solve the quadratic equation using the quadratic formula.

At the end, you will get side lengths of #(-14 ± 34) / 4, or -12 and 5

SInce a negative triangle length is impossible, 5 is the value of x and 5 + 7 is the value of x + 7, which makes 12.

The formula for area of a right triangle is A = bh/2

A = b(h)2

A= 12(5)2

A = 30cm^2

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
