WebExample 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°. WebOct 16, 2024 · In \(\triangle \)ABC, ∠B = 90°, AB = 12 cm and AC = 15 cm. D and E are points on AB and AC respectively such that ∠AED = 90° and DE = 3 cm then the area of \(\triangle \)ADE is Q9. If an angle is equal to one-fifth its compliment, then the angle is:
