Question
If a transversal intersects two parallel lines, and the
difference between two interior angles on the same side of the transversal is 40°, then find the smallest angle among the interior angles.Solution
Let the two interior angles on the same side of the transversal be x and y. Given, their difference is 20°.  x - y = 40° y = x -40°........(i) Since I and m are parallel and P is transversal 
Then, x + y = 180° ......[ Sum of interior angles is 180°] x + x -40° = 180° ...... [From equation (i)] 2x = 180° + 40° 2x = 220°  X =220°/2 = 110° Now, y = x -40° y = 110°-40° = 70° Smallest angles is 70° Therefore, the angles are 110° and 70°, respectively.

What approximate value should come in the place of (?) in the following questions?
∛(92.8 + √1025) * ? = 16.06% of 750
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
√784 × 3 + (713.99 ÷ 6.98) = ?% of 619.99
11.11% of (123.45 + 234.56) + 10.01³ - (5.05 of 7.07) = ? of (88.88 - 33.33)
