Q. the angles of triangle are in A.P. The greatest angle is twice the least. Find all the angles |
| Answer» Let the three angles of triangle which are in A.P. be a - d, a, a + dNow, sum of the angles = 180°{tex}\\Rightarrow{/tex}\xa0a - d + a+ a + d =\xa0180°{tex}\\Rightarrow{/tex}\xa03a = 180°{tex}\\Rightarrow{/tex}\xa0a = 60°It is given that,a + d= 2(a - d){tex}\\Rightarrow{/tex}\xa0a + d = 2a - 2d{tex}\\Rightarrow{/tex}\xa0a = 3d{tex}\\Rightarrow{/tex}\xa060° = 3d{tex}\\Rightarrow{/tex}\xa0d =\xa020°Thus, the angles of triangle are 40°, 60°, 80°. | |

Prove 3+√(5 is irrational |
| Answer» Let us assume, to the contrary, that is\xa0{tex}3 + \\sqrt { 5 }{/tex}\xa0rational.That is, we can find coprime integers a and b\xa0{tex}( b \\neq 0 ){/tex}\xa0such that{tex}3 + \\sqrt { 5 } = \\frac { a } { b } \\text { Therefore, } \\frac { a } { b } - 3 = \\sqrt { 5 }{/tex}{tex}\\Rightarrow \\frac { a - 3 b } { b } = \\sqrt { 5 }{/tex}{tex}\\Rightarrow \\frac { a - 3 b } { b } = \\sqrt { 5 } \\Rightarrow \\frac { a } { b } - \\frac { 3 } { 2 }{/tex}Since a and b are integers,We get\xa0{tex}\\frac { a } { b } - \\frac { 3 } { 2 }{/tex}\xa0is rational, also so\xa0{tex}\\sqrt { 5 }{/tex}\xa0is rational.But this contradicts the fact that\xa0{tex}\\sqrt { 5 }{/tex}\xa0is irrational.This contradiction\xa0arose because of our incorrect\xa0assumption that\xa0{tex}3 + \\sqrt { 5 }{/tex}\xa0is rational.So, we conclude that\xa0{tex}3 + \\sqrt { 5 }{/tex}\xa0is irrational. | |
