Bought for $20,000-$16000( present rate)=$4000 is the difference
$2000 is 10% of 20000 times 2 is $4000=answer
4. 5x+6.25
5.2x+40
6.3x+ -6
7. 1x+ 1/5
That's answer is false it not true
To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.
Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>
