Let the angles be x and (180-x).
Let 2x = 180-x.
Then 3x = 180, and x = 60. One angle is 60 degrees and the other is 180-60, or 120, degrees.
Answer:
127°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180°(n - 2) ← n is the number of sides
here n = 5 ( Pentagon), hence
sum = 180° × 3 = 540°
To find the fifth angle subtract the sum of the 4 given angles from 540
angle = 540° - (156 + 72 + 98 + 87) = 540° - 413° = 127°
312* 17.5= 5460.00
134*19=2546
2546+5460= $8,006.00
I think it is 2,504.
when you round 2,505 it comes out to 2,510.
Multiply everything by -3 so it will be n-15>4 then add 15 to both sides so it will be n>19 and thats the answer.
