Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
Answer:
2
Step-by-step explanation:
cuz u would have extra hats so just wear the pants again
we know that
in the right triangle ABC
the value of cosine of angle x is equal to

we have

substitute the values

Find the measure of angle x

Round to the nearest whole degree

therefore
<u>the answer is</u>

Answer:True
Step-by-step explanation:
Average speed refers to the total distance covered in a specific time . it also a scalar quantity (has magnitude but no direction)
Average speed=distance / time
-Speed is in kilometers/hours or meter/seconds
-distance is in kilometers or meters
-time is in hours or seconds
<em><u>45(x)-20 </u></em>
x=hours
7 hours
x=7
<em><u>45(7)-20 =295</u></em>
