Question

0.26. IF tanA = ¾
then find the value of 1/SinA + 1/ÇosA
यदि tanA = 74 हो तो 1/SinA + 1/CosA का मान ज्ञात कीजिए।
0 27. State and prove the basic nronortionality theorem​

Answer 1

Step-by-step explanation:

given TanA=3/4

we know that TanA=( opposite side to A)/(adjacent side to A)

from pythagorous theorem

hyp^2= adj^2+opp^ 2

hyp=√(3)^2+(4)^2

hyp=√25

hyp=5

now ,sinA= opp/hyp ;cosA=adj/hyp

sinA=3/5. ;cosA=4/5

1/sinA=5/3. 1/cosA=5/4

(1/sinA)+(1/cosA)=(5/3)+(5/4)

= 35/12
