According to the statement which you have to find value of , use identity (a+b)(a-b) = a^2 - b^2
Now in the numerator you have a= 1 , b= sin(theta)
Therefore you will have 1 - sin^2(theta) in the numerator
Similarly you will have 1- cos^2 (theta) in the denominator
Now there is an trigonometric identity according to which sin^2(theta) + cos^2(theta) =1
Therefore you will have cos^2(theta) in numerator [by substituting the values from above equation]
And sin^2(theta) in denominator [ by substituting the values from the above equation]
So finally you have to find the values of [cos^2(theta)]/[sin^2(theta)]
Which is equal to cot^2theta , (by simple trigonometric ratios )
Therefore now cot theta = alternate / opposite
But in the diagram which you have provided , it doesn’t contain any angle named as theta in the triangle
Now hope it may helped you , please mark this answer as brainiest answer if you understood, and plzz like it (iss gareeb ka kuch bhala karo yrr)
