Question

I need 3rd 4th questions
​

Answer 1

Answer:

3/5. 2/3

Step-by-step explanation:

tan A = perpendicular/base = 3/4

by Pythagoras theorem h²=p²+b²

h= hypotenuse= 5

sin A = 3/5

cos A = base / hypotenuse= 3/5

sec A is reciprocal of cos A

so, sec A=1/cosA = 5/3

as provided, 5/3-1 = 2/3

Answer 2

Answer:

:/ .. same here but looks like I got caught
