So basically ...
You convert the rupees in paisas. One rupee is equal to one hundred paisas, so ...
280 × 100 = 28,000
And then we divide,
28,000 ÷ 14 = 2000

Hope this helped! :)
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
50 dollars - 10 dollars
40 dollars is left.
Hey Astute!
Solve: x^2 - 18x = -72
Solution:
x^2 − 18x − (−72) = −72 − (−72) (Subtract -72 from both sides of the equation)
x^2 − 18x + 72 = 0
(x − 6) (x − 12) = 0 (Factor left side)
x − 6 = 0 or x − 12 = 0 (factors have to equal 0)
6 - 6 = 0 or 12 - 12 = 0
Answer:
x = 6 or x = 12
Hope This Helps, Have a Great Day!
