Bxngtan ⁷ 5 years, 6 months ago

Using the Formula, Each Interior angle of the Regular Polygon = [(n - 2) × 180] ÷ n 135° = (n - 2) × 180/n 180n - 360 = 135n 180n - 135n = 360 45n = 360 n = 360/45 n = 8 ∴ Number of Sides in the Regular Polygon is 8.

The digits of a two-digit number differ by 3. If the digits are interchanged, and the resulting number is added to the original number, we get 143. What can be the original number?

Jiya Wadhwa 5 years, 6 months ago

Let the two digit number be xy. The digit of a two digit number differ by 3. Hence, x - y = 3 ...(i) The digit are interchanged and the resulting number is added to the original number we get 143. 10x + y + 10y + x = 143 11x + 11y = 143 x + y = 13 ...(ii) Solving (i) and (ii) we get x = 8 and y = 5 Hence, the original number is 85.
