Question

Pls give step by step explanation of this question​

Answer 1

here is your answer

just rationalise the equation given which will help you to get the value but not in root

as tan¤ is given as 4/3 and tan¤ can be written as perpendicular/base

hope it helps

Answer 2

tan theta = 4/3 = p/b

p = 4, b = 3, h = ?

h = √ p^2 + b^2

h = √ 4^2 + 3^2

h = √ 16 + 9 = √ 25 = 5

√1 - sin theta /1 + sin theta

= √ 1 - p/h / 1 + p/h

= √ 1 - 4/5 / 1 + 4/5

= √ 5 - 4/5 / 5 + 4/5

= √ 1/5 / 9/5

= √ 1/9 =1/3

Hope this will help you...
