Question

cos A is equals to 5 by 13 evaluate Sin A minus cot a / 2tan A​

Answer 1

Answer:

Step-by-step explanation:cos A=5/13

We know that, sin^2A+cos^2A=1

sin^2A=1-cos^2A=1-(5/13)^2

sinA=12/13

cotA=cosA/sinA=5/12

2tanA=12/5×2=24/5

sinA-cotA/2tanA

(12/13-5/12)/(24/5)

(79/156)/(24/5)

79×5/156×29

395/4524
