Your answer is 1,087,508,000,000.
Answer:
Step-by-step explanation:
Given: 
To find: 
Solution:
From the image, 
Put 
Therefore,
BPD = 1/2(BD + CA)
BPD = 1/2(70 + 170)
BPD = 1/2(240)
BPD = 120
A full circle = 360 degrees
BC + AD = 360 - 70 - 170
BC+ AD = 360 - 240
BC + AD = 120
Expand the brackets: x²+5x+6=kx+2. So x²+(5-k)x=-4.
To complete the square on the left we add ((5-k)/2)² to each side:
(x+(5-k)/2)²=((5-k)/2)²-4.
Take a look at the right hand side: when this is zero we have equal roots:
((5-k)/2)²=4, (5-k)/2=±2, 5-k=±4, k=5∓4, giving us k=1 or 9.
(5-k)/2 is 2 or -2. So if k=9, (x-2)²=0. And x=2 is the positive root.
