A, B and C are three similar solids. The surface area of A is 24 centimetres squared

The surface area of B is 54 centimetres squared

The height of B : the height of C = 3 : 7

The volume of A is 72 centimetres cubed

C is made of wood with density 0.14 gram per centimetre cubed

Work out the mass of C

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
