Question

9. If cos A =4/5, then the value of
tan A is​

Answer 1

Answer:

Step-by-step explanation:

cos A = 4/5

Construct a right angled triangle and and represent the values of its sides. ( SO that it would be easy to get the values)

cos = adjacent/hypotenuse

tan = opposite/adjacent

SO the opposite side = √(hyp)² - (adj)²

opposite side = √25 - 16

opposite side = √9 = 3

tan A = 3/4.
