Question

What is the measure of an angle if it is 260 less than three times its own supplement

Answer 1

I feel like the answer is 70 degrees

Explanation:

3(180-x)-260=x

540-3x-260=x

-3x+280=x

280=4x

x=70

Answer 2

130 degrees

Explanation:

Let's assume that the angle is X. If angle is x, then:

x+260 = 3x

subtract x from both sides:

260 = 2x

130 = x because 260/2 is 130

so the answer is 130 degreees
