Thank you all for helping me ​

The diagonals of a rhombus are 12 inch and 16 inch long, the length of a side of a rhombus is 10 inch, what is the height of the rhombus

The step function g(x) is defined as shown.what is the range of g(x)? ***answer choices in picture.

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.
