Question 436486
4. Which is the best estimate for sin A?
A. 0.32(my answer) B. 0.42 C. 0.52 D. 0.62
1/pi =~ 0.32
---------------
5. Which is the best estimate for tan A?
A. 0.14(my answer) B. 0.24 C. 0.34 D. 0.44
It's less than 30 degrees, since the sine is <0.5
Sine and tangent are close for small angles, but the tan is always greater.
--> C 0.34
