Help me please i dont understand
1 answer:
So since they mentioned tangent I am guessing you need to use sin and cosine.
Usually we use sin, cosine and tan when we have an angle and we need to find one of the sides (look at the picture below)
But since now we have the sides and we need to find the angle, we need to use something called sin inverse or arcsin.
X=sin^-1 (6/14)
Note: sin^-1 is the same as saying sine inverse same as saying arcsin.
If we use this it will give us the required angle..
X=25.377 or X=25.4 degrees
Please do yourself a favour and compare it to the one below...finding the sides (because in the case we have the angle and not the sides we don’t use sine inverse)

Hey there!
Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C.
Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is
.
Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down.
The answer will be B, "a dilation with a scale factor of and then a translation."
Hope this helped you out! :-)
