Question

if an angle is 60 degree is less than two times of its supplement, then the smaller angle is

Answer 1

Define x:

Let one of the angle be x

The other angle = 2(180 - x) - 60

Solve x:

x + 2(180 - x) - 60 = 180

x + 360 - 2x - 60 = 180

300 - x = 180

x = 120

Find the angles:

One angle = x = 120º

The other angle = 180 - x = 180 - 120 = 60º

Answer: The smaller angle is 60º

Answer 2

In case the point is x, at that point its enhancement is 180 - x, isn't that so?

So we can state that x - 20 = 180 - x since we would need to subtract 20 from x to square with its enhancement.

So how about we include x, and furthermore add 20 to the two sides, so we presently get: 2x = 200, so x = 100 deg ANSWER Easy to check: x= 100,

so its enhancement = 180 - 100 = 80.

What's more, 100 is 20 more than 80.
