Question

If sin theta = 21/29, evaluate sec theta/ tan theta-sin theta

plz send the correct answer
​​

Answer 1

Step-by-step explanation:

sin theta = 21/29

opposite/ adjacent

Pythagoras theorem = (opp)*2+(adj)*2= (hyp)*2

(21)*2+(x) *2=(29)*2

(29)*2-(21)*2= 841-441= (x) *2

400=(x) *2

x(opp)= 20

sec theta/ tan theta - sin theta

29/20×21/29 = 29/20×20/21

= 29/21

29/21-21/29= 841-441/609

400/609

Hope this helps you

Answer 2

Answer:

841/189

Step-by-step explanation:

sin = 21/29 = perpendicular/hypotenuse

so base

= square root of hypotenuse- perpendicular

=square root of 21- 29

=20

so sec = 29/20 and tan =21/20

so sec/ tan - sin = 29/20/ 21/20- 21/29

=841/189
