I gave you the formulas for #1 and #2 when you posted under the name of Taylor

What part of just plugging in the above numbers do you have difficulties with ?
for #3, the diagonals of a rhombus bisect each other at right angles. Make a sketch to see 4 right-angled triangles, then use Pythagoras to find the length of the sides of the rhombus.
In #4, I have no clue where x is.
However, all angles can be found quite easily.
1.) what is the length of the line segment whose endpoints are (1,1) and (3,-3)?
2.) what are the coordinates of the midpoint of the line segment whose endpoints are (c,0) and (0,d)?
3.) The diagonals of a rhombus have lengths of 8 cm and 6 cm. The perimeter of the rhombus is?
4.) ABCD is a rectangle, E is a point on CD, the measure of angle DAE = 30 degrees and measure of angle CBE= 20 degrees. What is the measure of angle x?
