ABCD is a trapezium such that AB and CD are parallel and `B C_|_C D` . If `/_A D B""=theta,""B C""=""p""a n d""C D""=""q` , then AB is equal to (1) `(p^2+q^2costheta)/(pcostheta+qsintheta)` (2) `(p^2+q^2)/(p^2costheta+q^2sintheta)` (3) `((p^2+q^2)sintheta)/((pcostheta+qsintheta)^2)` (4) `((p^2+q^2)sintheta)/(pcostheta+qsintheta)`

ABCD is a trapezium such that AB and CD are parallel and BC bot CD . If angleADB = theta, BC = p and CD = q , then AB is equal to (a) ((p^(2)+q^(2))sin theta)/(p cos theta +q sin theta) (b) (p ^(2) + q ^(2)cos theta)/(p cos theta +q sin theta) (c) (p ^(2)+ q^(2))/(p^(2)cos theta +q^(2) sin theta) (d) ((p^(2) +q^(2))sin theta)/((p cos theta + sin theta)^(2))

If tan theta=(q)/(p) then find the value of (p sintheta+qcos theta)/(p cos theta+qsintheta)
