Question

if 15 cot a=8 find sin a, cos a, tan a,cosec a​

Answer 1

$.often that worker was doomed to\\ a life of poverty, since there\\ was often little in the way of\\ compensation for his or her injury.\\ The rise of occupational\\ medicine in the industrial era,\\ accompanied by an increased\\ recognition of occupational\\ hazards, led to improved\\ measures of protection for\\ workers.$

Answer 2

Answer:

15cotA=8

cotA=158

=> tanA=815-------(tanA=cotA1)

We know that,

tanθ=adjacentSideoppositeSide

Consider the attached figure, triangleABC

From Pythagoras theorem,

AC2=AB2+BC2

AC2=82+152=64+225=289

AC=17

cosA=HypotenuseadjacentSide=ACAB=178

secA=cosA1=1781817

sinA=
