if sin9degreesasin17degrees88 then a sin17degrees88sin9degre

if (sin9degrees/a)=(sin17degrees/88) then a= (sin17degrees/88sin9degrees). True or fals?

Solution

(sin9degrees/a)=(sin17degrees/88)

by crossmultiply

asin17degrees= 88sin9 degrees

divide both sides by sin17 degrees

we will get,

a= 88sin9 degrees/sin17 degrees

it means false
