Question

if tan A is equal to 8 upon 5 find the values of other trigonometric ratios​

Answer 1

Step-by-step explanation:

Here,

tanA=(8/5) ~tan60° & Perpendicular(p)=8

Base(b)=5

Let hypotenuse(h)=h

so,

sin60°=(p/h)=(8/h)

or,

sin60°=8/h

or,1 upon root under 2=8/h

or,h=8x root under 2

so, h= 11.31

so,

sinA= (p/h)=(8/11.31)=0.70

cosA=(b/h)=(5/11.31)=0.44

cotA=(b/p)=(5/8)=0.62

secA=(h/b)=(11.30/5)=2.26

cosecA=(h/p)=(11.30/8)=1.41
