.

( a )

BD = AD / tan(49°) = 60.0 / tan(49°)

DC = AD / tan(53°) = 60.0 / tan(53°)

w = BD + DC

w = 60.0 / tan(49°) + 60.0 / tan(53°)

w = 97.4 m

━━━━━

( b )

GJ = 5.5 / tan(40°)

HJ = 5.5 / tan(48°)

w = GJ - HJ

w = 5.5 / tan(40°) - 5.5 / tan(48°)

w = 1.6 m

You get one question per ticket. Here is the first.

w

= AD + DC

= 60/tan(49°) + 60/tan(53°)

≈ 97.4 m
