Question 449958
Find the measure of the given angles.
An angle whose supplement is 20" more than twice it's compliment.
assume you mean degrees, not seconds here
:
Let x = "the angle"
then
(90-x) = it's compliment
and
180-x) = it's supplement
:
Write an equation for the statement:
"An angle whose supplement is 20" more than twice it's compliment."
 (180-x) = 2(90-x) + 20
180 - x = 180 - 2x + 20
-x + 2x = 180 - 180 + 20
x = 20 degrees is the angle
:
:
see if that works
(180-20) = 2(90-20) + 20
160 = 2(70) + 20
