Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.
Answer:
420 (lol)
Step-by-step explanation:
Convert Miles to Yards:
yd =mi * 1760.0
Shown work:
mi -> yd
yd =mi * 1760.000
yd =0.5 * 1760.000
yd =880.0000
Result: 8.8e+2 OR simply just: <span>0.5mi= 880yd</span>
The change in temperature for 1 hour would be -5. hope this helps.
If two angles are complementary, then it they add up to 90 degrees.
<span>If they add up to 90 degrees, then they are right angles </span>
<span>So, If two angles are complementary, then they are right angles </span>
<span>Converse: If two angles add up to 90 degrees, then they are complementary. T </span>
<span>Inverse: If two angles are not complementary, then they do not add up to 90 degrees T </span>
<span>Contrapositive: If two angles do not add up to 90 degrees, then they are not complementary angles T </span>
<span>Hope this helps! ;D</span>
