Q1.The hypotenuse of a right angled triangle is 20 cm. The difference between its other two sides is 4 cm. Find the length of the sides. |
|
Answer» Answer: 19.6cm(20 cm) Step-by-step explanation: Let one of the sides be X then another side is 4 + x Applying Pythagoras theorem (20)² = (x)² + (x + 4)² 400 = x² + x² + 8x + 16 400 = 2x² + 8x + 16 2x² + 8x - 384 = 0 x² + 4x - 192 = 0 x² + 16x - 12x - 192 = 0 x(x + 16) - 12(x + 16) = 0 (x - 12)(x + 16) = 0 x= 12 or x = -16 But length can't be negative. So one of the side is 12 cm while the other is 16 cm You can verify this too! (12)² + (16)² = 144 + 256 = 400 Hypotenuse = √400 = 20 cm Hope This Helps You! |

Find x and y in parallelogram ABCD |
Answer» Answer:The value of X and y is 70° and 95° respectively. Explanation:Opposite angles of a parallelogram are equal. ∠A and ∠ B are opposite angles. ➞ ∠A = ∠B ➞ 3x - 20° = x + 40° ➞ 3x - x = 40° + 20° ➞ 2x = 60° ➞ x = 60°/2 ➞ x = 30° Value of x is 30° ADJACENT angles of a parallelogram are supplementary. ∠B and ∠C are adjacent angles. ➞ ∠B + ∠C = 180° ➞ y + 15° + x + 40° = 180° Substitute value of x ➞ y + 15° + 30° + 40° = 180° ➞ y + 85° = 180° ➞ y = 180° - 85° ➞ y = 95° Value of y is 95° |
