Question

If cos0=3/5, then find sin0-cot0/2tan0​

Answer 1

Step-by-step explanation:

for a right angle triangle if two side are 3 and 5 then another will be 4

cos theta = adjacent/hypotenuse = 3/5

so, 3 is adjacent side and 5 is hypotenuse and 4 is opposite side

sin theta = 4/5 = opposite/hypotenuse

cot theta = adj/opp = 3/4

tan theta = opp/adj = 4/3

substitute the the values you will get answer

Answer 2

Answer:

3/160

Step-by-step explanation:

sinA=1-cos^2

=1-(3/5)^2

=1-9/25

=16/25

sin0=4/5

cos0=3/5

tan0=sin0/cos0=4/5*5/3=4/3

=cot0=3/4

sin0-cot0/2tan0=4/5-3/4/(2(4/3))

=3/160
