Simplify : sq.root under 3 + 2sq.root2 |
| Answer» √(3 + 2√(2))=√(2 + 1 + 2√(2))(because 3 can be written as 2 + 1)=√(√(2)2 + 12 +2 √(2) 1)(because 2 can be written as √(2) 2 and 1 can be written as 1^2)It shows the identity: (a+b) 2 = a2 + b2 + 2abSo , it will become[√(2+1)] 2=(√2+1) 1/2*2=(√2+1) 1=√2+1 | |

The height of an equilateral triangle is 6cm.Find its area |
|
Answer» Altitude = Height = 6 cmLet length of side be \'a\'So , √3/2 a = 6So a = 12/√3So a = 4√3 cmThis \'a\' is the length of the sideNow, area = (√3/4) × a²So, Area = (√3/4) × (4√3)²So, Area = (√3/4) × (16×3)So, Area = ✓3 × 4 × 3So, Area = 12√3So, Area = 12×1.732So, Area = 20.784 cm²\xa0 1/2*base*height1/2*6*6=18 15.59 |

The angles of quadrilateral are in the ratio 3:5:9:13.find all the angles of the quadrilateral |
|
Answer» let angle be 3x,5x,9x,13x, by the angle sum property we will add this all as , 3x+5x+9x+13x =360 =30x =360 x =360/30 =12x =12 ,and now the number we get form this we will multiply with the given angles ,12×3 =36 ,12×5 =60 ,12×9 =108 ,12×13 =156 , Hence the required angle are , 36, 60, 108, 156 Let the angles be 3x,5x,9x,13x, theBy Angle sum property of quadrilateral3x + 5x + 9x + 13x = 360= 30x = 360 = x = 360/30 = 12x = 123x = 3×12(36)5x = 5×12(60)9x = 9×12(108)13x = 13×12(156)Requried number of the quadrilateral |
