Tamiko is planning a stone wall shaped like a triangle, with vertices (-1, -2), (2, 2), and (-2, 2) on a coordinate grid. She plans to add a second wall, in the same shape, enclosing the first wall, with the origin as the center of dilation. The vertices of the second wall are (-3, -6), (6, 6), and (-6, 6). What scale factor did Tamiko use for the second wall? Are the two walls similar? Explain

If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?

1) in triangle the, what is the measure of angle t (in degrees)? 2) in triangle bat, the measure of angle b is 66∘, and the measure of angle t is 77∘.what is the measure of the exterior angle at a (in degrees)?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
