Question

can someone explain to me how to solve this question
The measure of the supplement of an angle is 25% more than 7 times the measure of the angle. To the nearest hundredth, what is the measure of the angle?

Answer 1

i really dont know how to solve this problem and this is algebra 2

Answer 2

Well, supplemental angles add up to 180*.

so let your angle be x.

Write an expression for the supplement in terms of x. You know that "The measure of the supplement of an angle is 25% more than 7 times the measure of the angle"

So if x is the angle, then what is 7 times x?

Now, what is 25% MORE than 7 times x? (Keep in mind: you can write "25% more than a" as 1.25a).

Now, once you have your expression for the supplement, you ADD that to x and set it all equal to 180.

Solve for x, and you have the original angle, which is what is asked for. :)
