Answer:
X = 51
Step-by-step explanation:
24 + 27 = 51
x - 27 =
51 - 27 = 24
8% of their total bill = 3.70
0.08x = 3.70
x = 3.70/0.08
x = 46.25 <==
Answer:
The midpoint of AB = (x,y)=(1,1)
Step-by-step explanation:
Given : A line AB
To find : Midpoint of AB.
Solution :
Consider the figure
Then , Points of A = 
= (-2,0)
Points of B = 
= (4,2)
Now to find mid point we will use midpoint formula :
Thus, The midpoint of AB = (x,y)=(1,1)
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)
