Question

PLZZZZZZZZZZ. SOLVE THISS... PLZzzzzzzzzz​

Answer 1

Answer:

69.2 m

Step-by-step explanation:

let ABC be triangle where AB is 50m and the angle of elevation is 60 degree.

sin60=AB/AC

sin 60 = 60/AC

√3/2 = 60/AC

√3.AC =60.2

AC = 120/√3

AC = 40√3

AC = 40×1.73

AC = 69.2 m

Answer 2

Answer:

sin theta = p/h

sin 60 = 60/h

root3/2 = 60/h

h root3 = 60 × 2

h = 120 / root 3

rationalising

so h = 120 root 3 answer
