Answer:
Step-by-step explanation:
For this case we know that:
And we want to find the value for 
, so then we can use the following basic identity:
And if we solve for 
we got:
And if we replace the value given we got:
For our case we know that the angle is on the II quadrant, and on this quadrant we know that the sine is positive but the cosine is negative so then the correct answer for this case would be:
Use the sine law: sinB/b = sinA/a
SinB = b*sinA/a
sinB = 3*sin120° /8
∠ B = 18.94° ≈ 19°
Here is you're answer:
In order to get you're answer you need to find the common denominator then add.
- Find the common denominator:
- Simplify:
-
Therefore you're answer is option D "13/24."
Hope this helps!
asked:the istant of height is the same as the radius
given facts:cylindrical container with radius 3.5 inches height of rice increasing 0.5 inches per second
solve hidden given:(4.5+o.5+2)
what operation to be used: addition and subtraction
solve+4.5+05+2=6.0
chec: 6.0-4.5=1.5
The altitude's slope must be perpendicular to that of the line.
The slope of segment BC is 2/5. The slope of the altitude must be perpendicular to 2/5. Since the negative reciprocal of 2/5 is -5/2, then the slope of the altitude is -5/2.
