Answer:
3315 / 58√3315
Explanation:
From the question, you said that
Cosec A = 58 / 7
Cosec = 1 / sin and
Sin = opp / hyp, this means that
Cosec = hyp / opp with hypotenuse being 58 and opposite angle being 7
Using Pythagoras theorem, we know that
adj² = hyp² - opp²
adj² = 58² - 7²
adj² = 3364 - 49
adj² = 3315
adj = √3315
cos A = √3315 / 58, On rationalising the denominator, we have
√3315 / 58 * √3315 / √3315 =
3315 / 58√3315
