You can focus on the two sub-triangles ABC and ACD
We know that they are both right triangles, because we're given that AC and BD are perpendicular.
The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:
But since we're given 
, the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
(-2,3) to (2,-3)
6^2 + 4^2 = c^2
c = 7.21
————
(-2,3) to (1,5)
2^2 + 3^2 = c^2
c = 3.61
————
3.61 * 7.21 = approx. 26.03
The area is 26.03un^2
Answer:
16 - 2 = 14
Step-by-step explanation:
The lines mean absolute value and the absolute value of -16 is and of -2 is 2
Answer:
Positive 2
Step-by-step explanation:
its like ur subtracting 9+ (-7)
its basically 9-7=2
but not all problems r like this.
