Answer:

27 feet

Step-by-step explanation:

Total distance from base of lamp to tip of shadow

15 + 8 = 23

-------------------------

tan∅ = opp/adj

opp will be the height of the lamp

adj is 23

--------------------------

tan 50 = opp/23

multiply both sides by 23

23 * tan50 = opp

Use calculator

27.4 = opp
