Answer:
8 ft
Step-by-step explanation:
The area (A) of a triangle = 
bh
where b is the base and h the perpendicular height
Using b = 20 and h = 12, then
A = 0.5 × 20 × 12 = 120 ft²
Using b = 30 and perpendicular height = h, then
0.5 × 30 × h = 120
15h = 120 ( divide both sides by 15
h = 8

By definition of conditional probability,
P(<em>F</em> | <em>E</em> ) = P(<em>F</em> and <em>E</em> ) / P(<em>E</em> )
Then
P(<em>F</em> and <em>E </em>) = P(<em>F</em> | <em>E</em> ) P(<em>E </em>) = 0.5 • 0.2 = 0.1
