Write the rule for finding a point translated horizontally h units to the right use this rule to find the coordinates for (-3, -6) when translated 4 units to the right

In a column proof the right column states your reasons

Rhombus adef is inscribed into a triangle abc so that they share angle a and the vertex e lies on the side bc . what is the length of the side of the rhombus if ab=c, and ac=b.

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
