Sahil Verma 6 years, 2 months ago

Sol= Given that Sin 3A = cos (A-26°) We know that SinA= cos(90-A) SO, Cos( 90-3A)=cos(A-26°) 90+26= A+3A 116=4A A=116÷4 A=29. Ans

Sin3A=cos(90-3A). Then putting the value. Cos and Cos get cancelled then. 90-3A=A-26. Then 90+26=A+3A. 116=4A. A=116/4. A=29. -- answer

Aman Raza 6 years, 2 months ago

Let✓5 be rational Whose simplest form is a/b So, ✓5=a/b So, 5=a^2/b^2 So, a^2=5b^2 Here,5b^2 is divisible by 5 So, a^2is also divisible by 5 So,5is a factor of a Now, let's a=5c So, ( 5c)^2=5b^2 25c^2=5b^2 5c^2=b^2 Her,5c^2is divisible by 5 So,b^2is also divisible by 5 So,b is common factor for a And b So our supposison is wrong Hence✓5is irrational.
