Question

The measure of an angle is eighty-nine times it's supplementary angle. what is the measure of each angle.

I need two answers,

Answer 1

178 and 2

Explanation:

sum of supplementary angles are 180

so, x+ 89x = 180

=> x+89x = 180

=> 90x = 180 [the transposing method]

=> x = 180/90

=> x = 2

now we have the value of one angle

as the other angle is 89 times x,

=> 89x

=> 89*2

=> 178

now, we have the measure of both the angles which equals 180 degree

178 degree and 2 degree
