Web10 okt. 2024 · tan θ = 20 21 To do: We have to show that 1 − sin θ + cos θ 1 + sin θ + cos θ = 3 7. Solution: Let, in a triangle A B C right-angled at B and t a n θ = t a n A = 20 21. We … Web2 okt. 2015 · Tan theta = opposite side/adjacent side tan theta=1/root 7 Therefore, Opposite side=1 and Adjacent side= root 7 By Pythogoras theorem Hypotenuse^2=Adjacent^2+Opposite^2 Hypotenuse^2 = root 7^2 + 1^2 Hypotenuse^2 = 7+1 Hypotenuse = root 8 Sin theta = Opposite/ Hypotenuse Sin theta = 1/root 8 …
See: if tan theta=20/21,show that 1-sin theta+costheata /1+sin …
Web18 aug. 2024 · So comparing this formula and value of tan θ from question, we get : Height = 1 Base = √7 Now we need to Prove the value of : Also : From this we get : But we have Height and Base, we dont have Hypotenuse. Hypotenuse can be found by using Pythagoras Theorem Pythagoras Theorem states that : Hypotenuse² = Side² + Side² For our question : Web16 aug. 2024 · tan theta = 20/21 then p/b= 20/21 p= 20 b= 21 h= 20 square + 21 squareś whol root = 400 + 441ś whol root = whole root of 841 = 29 so we got p, b, h cos theta - sin theta / cos theta + sin theta =21/29 - 20/29. / 21/29 + 20/29 = 1/29 / 41/ 29 and the 29ś are cancelled we got = 1/41.
