Answer:i think its 80 cm
Step-by-step explanation:
Answer:
min f(x) = 3.95 (for x= 2.5)
Step-by-step explanation:
vertex (x) = 1/0,4 = 2,5
vertex (y) = 0.2(2.5)^2-2.5+5.2 = 3.95
Answer:
tan D =
or 0.545
tan F =
or 1.833
Step-by-step explanation:
To find tangent is always 
so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so
which is
or 0.545
The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so
is
or 1.833
