Answer #1

balloon problem

tan (theta) = ( h - 48.2) / x

tan 14.7 = (61.5 - 48.2)/x

x = 50.7 m

==========

as per law of cosine

cos (alpha) = ( b^2 + c^2 - a^2)/ ( 2 b*c)

cos alpha = ( 145^2 + 172^2 - 90^2) /( 2 * 145* 172)

alpha = 31.545

Similarly

cos (beta) = ( a^2 + c^2 - b^2)/( 2 a c)

cos (beta) = ( 90^2 + 172^2 - 145^2) / (2* 90*172)

beta = 57.44

again

cos( gamma) = ( a^2 + b^2 - c^2) / ( 2 ab)

cos ( gamma) = ( 90^2 + 145^2 - 172^2) / ( 2* 90* 145)

gamma = 91.015

========

Do comment in case any doubt, will reply for sure.. Goodluck
