Two angles of linear pair are such that one is half of the other. Find their measures |
|
Answer» Answer: Angles in a linear pair form a straight LINE with a total degree MEASURE of 180° If one angle in the pair is one HALF of the measure of the larger angle, we can relate them as such Smaller angle = x°
Larger angle = 2x°
given, the sum of the angles is 180°, so, x + 2x = 180°, => 3x = 180°, => x = 60° Therefore, the smaller angle be x° = 60°, and the larger angle be 2x° = 120°. |

The length, breadth and height of a rectangular solid are in ratio 5:4:2. If its total surface area is1216 cm2, find the volume of the solid. |
Answer» Given,that the ratio in length, breadth and height of a RECTANGULAR solid = 5 : 4 : 2 Total surface area =1216 cm² Let’s assume the length = 5x, breadth = 4x and height = 2X Total surface area = 2[5x × 4x + 4x × 2x + 2x × 5x] = 2[20x2 + 8x2 + 10x2 ] = 2 × 38x² = 76x² So, 76x² = 1216 ⇒ x² = 1216/76 = 16 = (4)² ∴ x = 4 Hence,the dimensions of the rectangular solid are Length = 5 × 4 = 20 cm Breadth = 4 × 4 = 16 cm Height = 2 × 4 = 8 cm and volume = lbh = 20 × 16 × 8 = 2560 cm³ |
