cotθ=125

Open in App
Solution

Given,

cotθ=125

tanθ=1cotθ=1125=512
We know that,

tanθ=oppositeSideadjacentSide=ABBC

Consider the figure above,

From Pythagoras theorem,

AC2=AB2+BC2

AC2=52+122

AC2=25+144=169

AC=13

sinθ=oppositeSideHypotenuse=513

cosθ=adjacentSideHypotenuse=1213

cscθ=1sinθ=1513=135

secθ=1cosθ=11213=1312
