Cosine is the ratio of the adjacent side to the hypotenuse.
In short, we have this equation
cos(angle) = adjacent/hypotenuse
In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5
The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)
So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5
Step-by-step explanation:
The mean is the average. Add up all the points, then divide by the number of points.
(12 + 17 + 11 + 13 + 17 + 15) / 6 = 14⅙
X^2+3x+3+[(2x^2+13+15)/(x+5)] is equivalent to option 4. im sorry if i got my math wrong but i hope this helps.
You have to do $1,790 reduced (decreased) by $395 times 800 and your answer is $1166,000
20 jasmine flowers? just do tally marks and count how many times you did them because each tally has five so you subtract the four from the five and count the tallys you have left
