Given that √2is irrational prove that 5-√3is and irrational number |
|
Answer» Bhai agar root 2 given h toh 5-root 2 hoga ya root 3 hoga glt h sawal Assume 5√3 to be Rational .....therefore it can be written in the form A/B right??So 5√3=a/b .........√3=a/5b.......here a /b is rational also dividing it by 5 it still stays rational that means rhs is rational but look carefully lhs is irrational.....therefore our contradiction is wrong 5√3 is irrational......also by logic rational * irrational will be irrational...... |

What is differes between rational or irrational |
|
Answer» Normal and simple difference is rational is terminating and non rational is non terminating Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers.In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.The rational number includes numbers that are perfect squares like 9, 16, 25 and so on. On the other hand, an irrational number includes surds like 2, 3, 5, etc. The rational number includes only those decimals, which are finite and repeating. Conversely, irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern. An irrational number is a number that cannot be expressed as a fraction for any integers and . Irrational numbers have decimal expansions that neither terminate nor become periodic. ... Numbers of the form are irrational unless is the th power of an integer. Rational no.. Are the no which can written in the form of p/ q where p and q are the intergers and q is not equal to 0 |

Value of tan 60 |
|
Answer» To find the value of tan 60 degrees geometrically, consider an equilateral triangle ABC since each of an angle in an equilateral triangle is 600.Therefore, ∠A = ∠B = ∠C = 60°Draw a perpendicular line AD from A to BC.Now consider the triangle, ABD and ADC,We have, ∠ ADB = ∠ADC= 90° and∠ ABD = ∠ACD= 60°Therefore, AD=ADAccording to AAS Congruency,Δ ABD ≅ Δ ACDFrom this, we can sayBD = DCLet us take, AB = BC =2aThen, BD= ½ (BC) =½ (2a) =aBy using Pythagoras theorem,AB2 = AD2– BD2AD2= AB2-BD2AD2 =(2a)2 – a2AD2 = 4a2-a2AD2 = 3a2Therefore, AD=a√3Now in triangle ADB,Tan 600= AD/BD= a√3/a = √3Therefore, tan 60 degrees exact value is given by,Tan 600=√3 √3 Root 3 √3 √3 1.732=tan60 √3 is the value of tan60 √3 |

Answer» hii Hii.. My pleasure....? Perimeter of minor sector = 2r + (2πr× thita)/360 Thank u soooo much.... Area of major segment = πr^2 - ( area of minor segment) Area of minor segment =( πr^2 × thita)/360 - 1/2× r^2 × sin thita its ok .... i can understand it??? Sorry...sorry...it\'s not arc...it\'s area of minor and major sector Sorry, area of minor arc = (πr^2 × thita)/360 and area of major arc = πr^2 ( 1- thita/360) Area of major arc = (πr^2 × thita )/ 360 Length of major arc = 2πr - (2πr × thita)/360° Length of minor arc =( 2πr× thita)/360° Thank u too much .. Area of ring = π(R^2 - r^2 ) Area of circle = πr^2 , Circumference of circle = 2πr , Area of semi- circle = πr^2/2 , Circumference of semi- circle = πr + 2r. Yes wait for while Area related to circles....all the formulas i want.. plz anyone.... |

If in a triangle angle ACB= angle CDA,AC=6 and AD=3 then find the lenth AB |
| Answer» The length of AB is 12 cm.Step-by-step explanation:Given data:∠ACB = ∠CDAAC = 6 cmAD = 3 cmTo find: Length of ABFrom the figure attached below, in ∆ ABC & ∆ ACD, we have∠A = ∠A ….. [∵ common angle for both the triangle]∠ACB = ∠CDA ….. [∵ given]∴ By AA similarity, ∆ABC ~ ∆ACDSince the sides of two similar triangles are proportional to each other∴ \\frac{AB}{AC} = \\frac{AC}{AD} = \\frac{BC}{CD}Now taking,\\frac{AB}{AC} = \\frac{AC}{AD}⇒ AC² = AB * AD⇒ 6² = AB * 3 …… [given AC = 6 cm & AD = 3 cm]⇒ 36 = AB * 3⇒ AB = 36/3 = 12 cm | |
