Q:
What are the values of cos α and tan α, if: sinα= 40/41
Accepted Solution
A:
Answer:The answer to your question is:cos α = 9/ 41tan α = 40/9Step-by-step explanation:Datacos α = ?tan α = ?sin α = 40/41Processsin Ф = opposite side / hypotenusethen, if sin α = 40/41,opposite side = 40hypotenuse = 41Pythagorean theorem c² = a² + b² 41² = 40² + b² b² = 41² - 40² b² = 1681 - 1600 b² = 81 b = 9adjacent side = 9Now,cosine Ф = adjacent side / hypotenusecos α = 9/ 41tangent Ф = opposite side / adjacent sidetan α = 40/9
