8.0
Step-by-step explanation:
The triangle is a right triangle, so we are able to use trigonometric functions. Relative to the angle of 37°, we have the opposite side which is 6 and the adjacent side which is x. The trig function that uses the opposite and adjacent is tangent(SohCahToa). We can set up the following equation:
tan(37) evaluates to about , so we can plug it in and solve for x:
To the nearest tenth, x rounds to 8.0.
Applying a dilation centered at the origin with scale factor has the effect of multiplying both coordinates of a point by
:
So, in your case, the coordinates of the points double:
