The measure of Angle A is 4 times greater than the measure of Angle B. The two angles are supplementary. Find the measure of Angle A.

a= 144, b=36

Step-by-step explanation:

x: the measure of angle a

y: the measure of angle b

(Set up a system of two equations)

(Use substitution; substitute 4b in for a)

(Simplify)

(Solve)

(Choose any original equation and plug in 36 in place of b; solve)

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.
