Answer:

i) sinA= 4/5

ii) cosA= 3/5

iii) tanA= 4/3

iv) sin^2A+cos^2A=1

Step-by-step explanation:

i) sec A= hypotenuse/addjacent= 5/3

opposite=√(5^2-4^2)= √16= 4

so, sinA= opposite/hypoteneous= 4/5

ii) cosA= addjacent/ hypotenous= 3/5

iii) tanA= opposite/addjacent= 4/3

iv) (sinA)^2+ (cosA)^2= (4/5)^2+ (3/5)^2= (16/25)+(9/25)=1
