Given:

Two triangles are given in the figure.

To find:

The m∠K and m∠J.

Solution:

In triangle FHK and IGJ,

         [Given]

         [Given]

Two corresponding angles are equal. So,

                  [By AA similarity theorem]

All corresponding angles of similar figures are same.

            ...(i)

Divide both sides by -2.

        ...(ii)

Taking square root on both sides.

Now,

          [Using (ii)]

       [Using (i)]

Therefore, the m∠K is 80° and m∠J is 80°.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
