Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
Answer:
20
Step-by-step explanation:
53 because there is only 2 sides of a penny so 105 divided by 2 is 52.5
For this case we have that by definition, the surface area of a cone is given by:
Where:
r: It is the cone radius
s: It's the slant height
According to the data we have:
Substituting:
Thus, the surface area of the cone is
