We know that
The Intersecting Chord Theorem, established that "<span>When two chords intersect each other inside a circle, the products of their segments are equal."
</span>so
(n+2)*16=(n+8)*8
16n+32=8n+64
16n-8n=64-32
8n=32
n=32/8
n=4
the answer is
n=4
So speed = distance divided by time, therefore 70 miles divided by 35 minutes = 120mph. The speedboats speed was 120mph.
Hope this helps
Answer:
the sum of all three angles is 180° in every plane triangle.
knowing that we know that the upper right angle is 180-99-37 = 44
do it follows:
-x-5 = 44
and
-x = 49
and there
x is -49
please please please brainliest (if you like the answer)
Answer:
1/4
Step-by-step explanation:
The slope of a line is the steepness of a line.
The slope of a perpendicular line is always the negative reciprocal of the slope of the line it is perpendicular with.
Since line C has a slope of -4, the negative reciprocal of that is 1/4.
Reciprocals are two numbers that multiply together to get 1.
For example, -1/4*-4/1=1
Therefore the negative recipricol is 1/4
