First add both equations, we'll get 244x+244y=244, Now, Divide this equation by 244, it gives x+y=1.....(a) Again, subtract equation 2 from 1, it gives 38x-38y=190, Now, divide this equation by 38,comes x-y=5.....(b) Now add equation (a)and(b), implies 2x=6 we get x=3 Now put the value of x in (a),...

141x+103y=217 ..........(1) 103x+141y=27..............(2) Add (1) and (2). So, (1) + (2) is 244x + 244y=244 -> x + y=1 ................(3) Subtract (2) from (1). So, (1) - (2) gives 38x - 38y=190 -> x - y =5......................(4) Now, the two simplified equations are x + y = 1..........(3) x...

Again, (3) - (4) gives 2y = -4 or y = -2. read less

What is the value of Sin360+Cos360?
Sin(360)= sin(0)=0 Cos(360)=cos(0)=1 Formula: Sin((360*x)+y)=sin(y) Cos((360*x)+y)=cos(y) Where x is any integer and y is any real number. Sin(360) +cos (360) =1

Hello everyone

Which is better? : Online tuitions by brands like: Meritnation, Myschool page or Catalyze or regular tuition classes?
I would suggest offline coaching because it binds the students and gives different levels of class surrounding, which is not possible in online classes. However, for extra self-studies, one can take the help of online material.

How many triangles can be drawn having its angles as 45°, 64° and 72°? Give reason for your answer.
Zero triangles.. we cant draw triangle with these angles. but the given angles are 45,64.72. if we add those we get 45+64+72=181. so we cannot draw triangle.
