If cosec A + cotA = p , then prove that cosA = p2 - 1/p2 + 1 |
| Answer» cosec A + cot A = p{tex}\\frac{1}{sinA}{/tex}\xa0+ {tex}\\frac{cosA}{sinA}{/tex}= p1 + cosA = psinASquaring both the sides(1 + cosA)2 = p2 (sinA)2(1 + cosA)2 = p2 (1 - (cos)2)(1 + cosA)2 = p2 (1 - (cos)) (1+cosA)1 + cosA = p2 (1 - cosA)cosA = (p2-1)/(p2+1)Hence proved | |

Prove converse basic propotionality theorem |
|
Answer» Converse of Basic Proportionality TheoremStatement If a line divides any two sides of a triangle (Δ) in the same ratio, then the line must be parallel (||) to the third side.DiagramGiven In ΔABC, D and E are the two points of AB and AC respectively, such that, AD/DB = AE/EC.To Prove DE || BCProof In ΔABC, given, AD/DB = AE/EC ----- (1) Let us assume that in ΔABC, the point F is an intersect on the side AC. So we can apply the Thales Theorem, AD/DB = AF/FC ----- (2) Simplify, in (1) and (2) ==> AE/EC = AF/FC Add 1 on both sides, ==> (AE/EC) + 1 = (AF/FC) + 1 ==> (AE+EC)/EC = (AF+FC)/FC ==> AC/EC = AC/FC ==> EC = FC From the above, we can say that the points E and F coincide on AC. i.e., DF coincides with DE. Since DF is parallel to BC, DE is also parallel BC Hence the Converse of Basic Proportionality therorem is proved Ex14.1 |

Find the zeroes of integers between 10 and 500 which are divisible by 7 ? |
|
Answer» So, the sum of integers between 10 and 500 is 17885. AP are : 14 , 21 , 28 ......497 . So, a= 14 , Tn = 497 , d= 7 . Now, Tn = a + (n-1) d => 497 = 14 +(n-1) 7 => n= 70 . Sn = n/2 ( Tn + a) => Sn = 70/2 ( 497+14) => Sn = 35× 511 => Sn = 17885 . |

Solve for x and y : 37x+43y = 123. , 43x + 37y =117 |
|
Answer» So, y= 2 and x= 1 37x + 43y = 123...(1) , 43x + 37y = 117....(2) , Adding (1) and (2) , we get, 80x + 80y = 240 => x+y = 3.....(3) , Subtracting (2) from (1) , we get, -6x +6y = 6 => -x+y = 1 .....(4) . Adding (3) and (4) , we get, 2y= 4 => y = 2 . Now, put the value of y in (3) , we get, x = 1. |
