Answer: All Real Numbers
x2−8x+17>0
x2−8x+17=0
For this equation: a=1, b=-8, c=17
1x2+−8x+17=0
x=
−b±√b2−4ac
2a
(Use quadratic formula with a=1, b=-8, c=17)
x=
−(−8)±√(−8)2−4(1)(17)
2(1)
x=
8±√−4
2
All real numbers
Answer:
do no i just need points
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
We will prove first that PRQ≡PSQ
We need 3 attributes from the each triangle:
QS=QR
PR=PS
PQ=PQ
from PRQ≡PSQ => angles RPQ and SPQ are equal
Let if be O=RS∩PQ
We will prove that triangles RPO≡SPO
We need 3 attributes from the each triangle:
RP=PS
PO=PO
angles RPQ and SPQ are equal
results that angles RPO and SPO are equal(Let's note them with x)
We also know that (as angles) POS≡ROS and POR≡SOQ as opposite angles
We now have than 4x=360 wich means x=90. And we proved the desired result.
You just need to put this explanation into the table. (most if the 3 attributes for each triangle)
The answer is C make it half, you will always get the other half of the number
