Question

pls solve it guys correct answer be brainlist​

Answer 1

Answer:

cos A = 9 / 41

= adjacent / hypotenuse

adjacent = 9

hypotenuse = 41

by pythagorous theoram ,

${x}^{2} = 41 {}^{2} - 9 {}^{2} \\ x {}^{2} = 1681 - 81 \\ x {}^{2} = 1600 \\ x = 40$

Opposite = 40

tanA = opposite / adjacent

= 40 / 9

Mark me brainliest pls

Answer 2

Answer:

tan A = 40/9 is your answer

cos A= 9/41

so, we know that ,

cos^2 A + sin^2 A = 1

(9/41)^2 + sin^2 A = 1

81/1681 + sin^2 A = 1

sin^2 A = 1 - 81/1681

sin^2 A = 1681 - 81/ 1681

sin^2 A = 1600/1681

sin A = 41/40

tan A = 40/9

mark as brain list...
