Answer:
I believe it is 1.) SAS (angle side angle) 2.) SSA (side side angle), but can not be proven as a postulate, so not enough information, 3.) SAS (side angle side) 4.) SSS (side side side)
Step-by-step explanation:
Answer: This is impossible because the absolute value function can never result in a negative number.
You should use a calculator this is very easy, you just add up the things in common and then then divide
Answer:
3(n + 4) ≤ 10 is the equation and the solution is n ≤ -2/3 Decimal Form: -0.666667
hope this helps you
Step-by-step explanation:
It would be easier to explain if the vertices were labeled.
Let's call the horizontal diagonal of the kite c.
The area of the triangle with sides
triangle is given by

c itself is given by the Law of Cosines:

At this point I'd use a variation on Heron's formula to calculate the area. But the question says to use the sine and cosine rules so we'll do it that way.
The opposite angle, call it D, is given by the law of Cosines. We need its sine so we don't actually have to calculate the angle:



Now the other triangle has area

So we get a total area of
