Answer:
Denote the two points are A and B, the balloon is C. Then we have,
Side AB = 9 miles
Angle CAB (angle A) = 27 deg
Ange CBA (angle B) = 45 deg
=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg
Applying the sine theorem:
AB/sinC = BC/sinA
=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles
Denote CH as the height from C to side AB (or distance from ground to balloon), we have:
CH = BC x sin B = 4.3 x sin*45 = ~3.04 miles
=> Distance from ground to balloon: ~3.04 miles
Hope this helps!

Answer:
3.0 miles
Step-by-step explanation:
Let h be the height
Tan(27) = h/b
h = btan(27)
Tan(45) = h/(9-b)
(9-b)tan(45) = h
(9-b)tan(45) = btan(27)
9tan(45) = b[tan(45) + tan(27)]
b = 5.962138633
h = btan(27) = 3.037861367
