Answer:
h = 110°
Step-by-step explanation:
1) A pentagon has 5 sides that sum up to 540°. We know it is 540° because of this formula that is used to find the sum of the interior angles of any polygons. <u>n</u> is the number of sides.
= (n - 2) x 180
= (5 - 2) x 180
= 3 x 180
= 540°
2) We can now set up an equation.
70 + 100 + 120 + 140 + h = 540
430 + h = 540
h = 540 - 430
h = 110°
I'm not sure but if I'm right I think it's 5.3 pounds would be 12.5 which is the closest to 12.64.
Again, not sure. If you know the right answer, I'd like to know it please. :]
