Supplementary Angles math problem?

Question

Two angles are supplementary if the sum of the measures of the angles is 180 degrees. If one angle is 30 degrees more than its supplement, find the measures of the two angles.

anybody know?

Answer 1

x + x + 30 = 180

2x +30 = 180

2x = 150

x = 75

75 + 30 = 105

105 + 75 = 180

Answer 2

105 and 75

plz help me

Answer 3

x + y = 180

x = 30 + y

30 + y + y = 180

2y + 30 = 180

2y = 150

y = 75

x = 105

Answer 4

One is 105 degrees the other is 75 degrees

Hope that helps

Answer 5

When are you teenagers gonna realize that Yahoo Answers is not a math tutor?  

Answer 6

105 and 75, easiest way is x+(x+30)=180

Answer 7

105 degrees!!

did that like 3 yrs ago!

Answer 8

One angle is 30 + x.

The second angle is x.

30 + x + x = 180

2x + 30 = 180

2x = 180 - 30

2x = 150

x = 150/2

x = 75 degrees.

30 + x = 30 + 75 = 105 degrees.

Check: 75 degrees + 105 degrees = 180 degrees.

I hope that helps. :)

Answer 9

75 and 105

Answer 10

The equation would be 180= x + (30+ x)

x would the measure of the smaller angle

and "30 + x" would be the measure of the larger one, which would be the measure of the smaller angle plus 30 as stated

And you solve for x

Answer 11

Let the angle be A.  Then its supplement is 180 - A.

But A is 30 degrees more than the supplement, so

A = (180 - A) + 30

2A = 210

A = 105

180 - 105 = 75

So the angles are 75 and 105.

Answer 12

do it your self its for your own good so you can l-e-a-r-n!

Answer 13

okay follow these instructions to get the answer:

1. Take 30 off 180 to get 150

2. Divide 150 by 2 to get 75

3. So now one angle is 75 and the other is:

4. 75 plus 30 which is 105.

(now one angle is 75 and the other is 105. the total is 180 and one angle is 30 degrees more than the other)

hope this is helpful!
