Please help me I will give brainlest to first answer!!!

What value of x will make the triangles similar by the sss similarity theorem?

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
