Which of the following is the same as 8.4x10²

For this case we must find an expression equivalent to:

We must run the decimal two spaces to the right, then:

If we run a space on the right we have 84, so when running two spaces on the right we have: 840

Thus, 8400 is an expression equivalent to

840

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.
