In a triangle `A B C ,a : b : c=4:5: 6.` Then `3A+B` equals to: `4C` b. `2pi` c.`pi-C` d. `pi`

In a triangle ABC,a:b:c=4:5:6. Then 3A+B equals to: 4C b.2 pi c. pi-Cd. pi

If in a triangle ABC , a= 5 , b=4 , A = (pi)/(2) +B, then C:

If in a triangle ABC , a=5,b=4 ,A = (pi)/( 2) +B then C

In a triangle ABC if A-B=(pi)/(2) , then C+2B is equal to

In any triangle A B C ,\ sin A-cos B=cos C ,\ the angle \ B is a. pi/2 b. pi/3 c. pi/4 d. pi/6

If in a triangle A B C, a=5, b=4, A=(pi)/(2)+B , then the value of C is

In a triangleA B C ,/_B=90^0 and b+a=4. The area of the triangle is maximum when /_C is (a) pi/4 (b) pi/6 (c) pi/3 (d) none of these

In a triangleA B C ,/_B=90^0 and b+a=4. The area of the triangle is maximum when /_C is (a) pi/4 (b) pi/6 (c) pi/3 (d) none of these

In any triangle ABC,sin A-cos B=cos C, the angle B is a.(pi)/(2) b.(pi)/(3) c.(pi)/(4) d.(pi)/(6)
