Answer:
156
Step-by-step explanation:
x - √+ = 12
= 12^2= 144
x = 144
For this, we are just going to plug in -9 for every x and then solve the equation:




Now we know that q(-9) is equal to 566.
It is clear that (AB) is a median, and it is obvious that the angle is 90, thus it is an altitude and a perpendicular bisector
Answer:
X=30
The whole triangle = 180 degrees
