Question

in triangle ABC right angled at B if AB=4 and BC=3 find all the six trignometric ratio​

Answer 1

Answer:

sintheta= 4/5, costheta=3/5, tantheta =4/3,cosec theta=5/4,sectheta =5/3 and cottheta =3/4

Step-by-step explanation:

• ZB=90
• AB=4,BC= 3
• AC^2=AB^2+BC^2(Pythagoras theorem

• AC^2=(4)^2+(3)^2
• AC^2=16+9
• AC^2=25
• AC=√25
• AC=5

sintheta=AB/AC=4/5

costheta=BC/AC=3/5

tantheta=AB/BC=4/3

cosec theta=AC/AB=5/4

sectheta =AC/BC=5/3

cottheta =BC/AB=3/4

• HENCE, THESE ARE ALL TRIGNOMETRY RATIOS.
