If tan theta is -1, we know immediately that theta is in either Quadrant II or Q IV. We need to focus on Q IV due to the restrictions on theta.
Because tan theta is -1, the ray representing theta makes a 45 degree angle with the horiz axis, and a 45 degree angle with the negative vert. axis. Thus the hypotenuse, by the Pythagorean Theorem, tells us that the hyp is sqrt(2).
Thus, the cosine of theta is adj / hyp, or +1 / sqrt(2), or [sqrt(2)]/2
The secant of theta is the reciprocal of that, and thus is
2 sqrt(2)
---------- * ------------ = sqrt(2) (answer)
sqrt(2) sqrt(2)
To find the side length of a cube with a volume of 343, you need to find m to the third power. Solve that and you get 7. m = 7
Answer:
A and E
Step-by-step explanation:
Check the picture below.
make sure your calculator is in Degree mode.
Add 8 to 46. Then divide 54/8 to get 6.75 and t=6.75
