Question

if 5 cot A=12, find the value of cosec A+ sec A​

Answer 1

Answer:

221/60

Step-by-step explanation:

5 cot A = 12

cot A = 12/5 = Base / Perpendicular

Using Pythagoras theorem

H² = B² + P²

    = √[(12)² + (5)²] = √[144 + 25] = √169 = 13

Now, cosec A = H/P = 13/5

sec A = 13/12

Now, cosec A + sec A = 13/5 + 13/12 = (156 + 65)/60 = 221/60

Remember to not convert cosec in sin and sec in cos otherwise, you will find the answer for sin + cos not for cosec + sec

however, you will get different answers

Answer 2

Answer:

5cotθ=12

∴cotθ=512

∴1+25144=cosec2θ

∴cosecθ=25169=513

∴1+14425=sec2θ

∴secθ=144169=1213

1213+513=6065+156

=60/221
