Answer: Rhombus and square</h3>
Explanation:
Any rhombus has its diagonals meet at 90 degree angles. The proof for this is a bit lengthy, so I'll let you handle it. The basic idea is to draw in the diagonals, which forms smaller triangles. Proving those triangles to be congruent leads to supplementary congruent angles, which in turn leads to the 90 degree angles needed.
A square is a special type of rhombus where all four angles are the same (each 90 degrees). Put another way, a square is both a rectangle and a rhombus at the same time.
Some rectangles are not squares, so the non-square rectangles will have the diagonals not be perpendicular.
Domain of f of g.
Determine domain of g.
x + 4 ≥ 0
x ≥ -4
Now determine domain of f of g, by first figuring out f of g:

So x ≠ 3
So our domain is
[-4, -3) ∪ (-3, ∞)
The answer is D.
Answer:
Step-by-step explanation:
Cross multiply and get:
L = 5w
L = 5w/
W =
L/5
Because this triangle is an Isosceles triangle, two of the angles will be the same. You can tell this is an Isosceles triangle because two sides have the same length but the other does not. You can use this to make an equation. Because a triangle has 180 degrees all together, you can use the equation 2x+56=180. To solve for X you first do 180-56. You will get 124. Now you have 2x=124. You then divide 124 by 2. You will then get 62. This means X = 62 or 62 degrees. The final answer will be X = 62 Degrees.
