Prove that √7 is an irrational |
|
Answer» Answer: Step-by-step EXPLANATION: √7 = p / q √7 x q = p squaring on both sides 7q² = p² ------1. p is divisible by 7 p = 7c [c is a POSITIVE integer] [squaring on both sides ] p²= 49c² subsitute p² in eqn(1) we get 7q² = 49 c² q² = 7c² q is divisble by 7 thus q and p have a common factor 7. there is a contradiction to our assumption as our assumsion p & q are co prime but it has a common factor. so that √7 is an IRRATIONAL. |

in a triangle ABC AB perpendicular BC angle ACB is equal to 30 degree ab is equal to 50 then find the length of BC why you not take sin 30 degree |
|
Answer» Answer: In △ABC AB=AC ⇒∠B=∠C (Angles opposite to EQUAL sides are equal) Now using angle sum property ∠A+∠B+∠C=180 ∘
⇒80 ∘ +∠C+∠C=180 ∘
⇒2∠C=180 ∘ −80 ∘
⇒∠C= 2 100 ∘
=50 ∘
now ∠C+∠x=180 ∘ (Angles made on straight line (AC) are supplementary) ⇒50 ∘ +∠x=180 ∘
⇒∠x=180 ∘ −50 ∘ =130 ∘ |
