triangle ABC, right angled at B, If tan A = 4/3 , then the value of cos C is 1 point (a) 3/5 (b) 4/5 (c) 1 (d) none of these Other:
Answers
Answer:
3/5
Explanation:
tan A=perpendicular/base=4/3
As it is right angle triangle use Pythagoras theorem to find hypotenuse that will be 5
cos A= base/hypotenuse=3/5
Answer:
4/5
Explanation:
tanA = 4/3 So, AB = 3cm, BC = 4cm and AC = ? In triangle ABC, By pythagoras theorem, we have AC² = AB²+BC² AC² = (3)² + (4)² AC = 9 + 16 AC² = 25 AC = √25 AC = 5cm cosC = B/H = 4/5 The correct answer is 4/5 Thankyou
