HCF of 96 and 404 by prime factorisation method:-
Since, 96 = 2 × 2 × 2 × 2 × 2 × 3
and, 404 = 2 × 2 × 101
So, HCF of 96 and 404 = Product of common prime factors
= 2 × 2 = 4
LCM = 2 × 2 × 2 × 2 × 2 × 101 × 3
= 9696

Here in a triangle, given, ✓C=90° angleA+angleB+angleclC=180° . Then, ✓A+✓B=180°-C. => Cos(A+B)= Cos90° => Cos (A+B)=0.

? Pranali.A.P ? 5 years, 5 months ago

since ABC is right angled and angle C is 90° therefore, A+B=180° - C A+B=180°-90° A+B= 90° Therefore,cos (A+B)=cos90° =0

Let the consecutive no. be x and (x+1) then,A/q, x(x+1)=306 => x²+x-306 => x²-17x+18x-306 => x(x-17)+18(x-17) => (x-17)(x+18) => x=17 or -18

? Pranali.A.P ? 5 years, 5 months ago

Let two consecutive numbers are x and (x + 1) A/C to question, product of x and (x + 1) = 306 ⇒x(x + 1) = 306 ⇒x² + x - 306 = 0 ⇒ x² + 18x - 17x - 306 = 0 ⇒x(x + 18) - 17(x + 18) = 0 ⇒(x + 18)(x - 17) = 0⇒ x = 17 and -18 Hence, numbers are x = 17 and (x +1) = 18

3x /2-5y/ 3= -2 ,. On taking LCM and simplification, we get 9x - 10y = -12 ....(1 ) On simplification, 2x + 3y = 13 ......... (2) Multiply the (1) by 3 and the equation (2) by 10 27x - 30y = -36 20x + 30y = 130 Adding both equations, we get 47x = 94 x = 2 Substitute x = 2 in equation (2) 2(2) + 3y = 13 3y = 9 y = 3 4.
