I dont know this one sorry
Answer: AAS
Step-by-step explanation:
P(7,6), Q(1,6), R(4,2)
We have PQ parallel to the x axis. We'll call that the base,
b = 7 - 1 = 6
The altitude is then the y difference h = 6 - 2 = 4
The area is 
Answer: 12 square units
In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:
(7,6), (1,6), (4,2)
(1,6), (4,2), (7,6)
The area is then half the absolute value of the sum of the cross products:

x=1001+75.55x
Simplify
x=<span><span>75.55x</span>+1001</span>
Subtract
x−<span>75.55x</span>=<span><span><span>75.55x</span>+1001</span>−<span>75.55x</span></span>
−<span>74.55x</span>=1001
Divide
<span><span>−<span>74.55x/</span></span><span>−74.55 = </span></span>
<span><span><span><span><span>1001/<span>−74.55</span></span><span><span>your answer is:</span></span><span>x=<span>−<span>13.42723</span></span></span></span></span></span></span>
