Step-by-step explanation:
Answer:
4.72 in.
Step-by-step explanation:
BC = 3.1 in.
CD = 7.2 in.
Altitude of right triangle altitude is given as 
, where:
h = altitude
x = 3.1 in.
y = 7.2 in.
Plug in the values into the formula
(nearest hundred)
X-10 = 0 results in x = 10, and x + 8 = 0 results in x = -8.
The two solutions are x = 10 and x = -8
