∠ a: x
∠ b: x
∠ c: x + 21
∠ d: x - 53
∠ a + ∠ b + ∠ c + ∠ d = 360 <em>sum of the angles of a rectangle is 360° </em>
(x) + (x) + (x + 21) + (x - 53) = 360
4x - 32 = 360
4x = 392
x = 98
∠ c: x + 21 = (98) + 21 = 119
∠ d: x - 53 = (98) - 53 = 45
Answer: ∠ a = 98°, ∠ b = 89°, ∠ c = 119°, ∠ d = 45°
5^11 + 5^10
------------------- =
5^10 - 5^8
48,828,125 + 5^10
-------------------------- =
5^10 - 5^8
48,828,125 + 9,765,625
--------------------------------- =
5^10 - 5^8
48,828,125 + 9,765,625
----------------------------------- =
9,765,625 - 5^8
48,828,125 + 9,765,625
--------------------------------- =
9,765,625 - 390,625
58,593,750
------------------------------ =
9,765,625 - 390,625
58,593,750
------------------ =
9,375,000
answer: 6.25
The awnser would be .48 hope this helps
