Someone please help me answer this
vichka [17]

Answer:

a = 6.7m is the answer.

Step-by-step explanation:

a = ?

b = 6m

c = 9m

According to the Pythagorean theorem,

a² + b² = c²

a² + 6² = 9²

a² + 36 = 81

a² = 81 - 36

a² = 45

a = 6.708

round to the nearest tenth,

a = 6.7m

∴ Janice is 6.7m high up in the air.
