Question

if tan theta=3/4,,find the value of 1-cos theta/1+cos theta

Answer 1

this is the solution of ur question

Answer 2

1/9 is the value of 1-cos theta/1+cos theta

Step-by-step explanation:

tan∅ = 3/4 = P/B

∵ P = 3K, B = 4k

∵ H = $\sqrt{(3K)^{2} + (4K)^{2} }$

= $\sqrt{(9K)^{2} + (16K)^{2} }$

= $\sqrt{25K^{2} }$

H = 5K

∵ Cos∅ = B/H

= 4K/5K = 4/5

∵ $\frac{1-cos∅}{1 + cos∅}$ = (1 - 4/5)/1 + 4/5

= 1/9
