Ответ:
cosine of 53° = sin 37°
Step-by-step explanation:
In a right angle triangle we have to find the cosine of angle if value of sin 37° is equal to the cosine of that angle.
In a right angle triangle ABC, if sin B = sin 37° =![\frac{Height}{Hypotenuse}=\frac{AB}{AC}](/tpl/images/0429/6608/d166e.png)
Or we can say cos B = cos 53° =![=\frac{Base}{Hypotenuse}=\frac{AB}{AC}](/tpl/images/0429/6608/e7002.png)
Therefore cosine of 54° will be equal to sine of 37°
