Hello!
These are the following formulas to calculate sine, cosine, and tangent.
sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent
To find sin(B), we need to find the side opposite of angle B, and the hypotenuse.
The opposite of angle B is 12, and the hypotenuse is 13.
sin(B) = 12/13
sin^-1(12/13) = 67.3801... This can be rounded to 67.38 degrees. (Tenths place: 67.4 degrees)
To find cos(B), we need to find the side adjacent of angle B, and the hypotenuse.
The adjacent side of angle B is 5, and the hypotenuse is 13.
cos(B) = 5/13
cos^-1(5/13) = 67.3801... It can be rounded to 67.38 degrees. Rounded to the tenths place is 67.4 degrees.
To find cos(B), we need to find the side adjacent and opposite of angle B.
The adjacent side of angle B is 5, and the opposite is 12.
tan(B) = (12/5)
tan^-1(12/5) = 67.3801... This can be rounded to about 67.38 degrees. Rounded to the tenths place is 67.4 degrees.
Therefore, the value of sin(B) is 67.38 degrees, the value of cos(B) is 67.38 degrees, and finally the value of tan(B) is 67.38 degrees.
Answer:
The correct answer is B (4,-5)
Step-by-step explanation:
Each increment goes down by 2.5, so the only choice that really matches is B. (4,-5)
BC= 30
Reason: 64-8
56/7
8=x
3x=24
24+6
30
4x - 6y = 12...in y = mx + b form, the slope will be in the m position. So lets turn this equation into y = mx + b form.
4x - 6y = 12....subtract 4x from both sides
-6y = -4x + 12...now divide both sides by -6
y = (-4/-6)x + 12/-6
y = 2/3x - 2...y = mx + b.....slope(m) = 2/3 <==

I’m pretty sure the 57th term would be 505. You would just add 9.
