Answer:
sin a=3/5
cos a=4/5
Step-by-step explanation:
<u>sin</u> <u>A</u>
AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)
AB (squared)=16+9
AB (you must put a square root over AB)=25(remember 25 is now a square root)
AB=5
sin a=opposite/hypotenuse
=3/5
<u>cos A</u>
cos a=adjacent/hypotenuse
=4/5
I believe the answer is A
but i’m not 100% sure
I believe it’s called friction
ANSWER
The greatest common divisor of 15,015 and 495 is 165.
<u>EXPLANATION</u>
We use the Euclidean Algorithm to compute the Greatest Common Divisor as follows;


The last remainder before zero is the greatest common divisor.
Therefore
