Answer:
9/22
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−9/4 ÷ −11/2
Applying the fractions formula for division,
=−9×2 divided by 4×−11
=−18/−44
Simplifying -18/-44, the answer is
=9/22
Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.
Let x = angle of elevation.
By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)

Answer:
r = 14.5
Step-by-step explanation:
AD is the perpendicular bisector of chord EC, so is the diameter of the circle. The radius is half the diameter.
r = AD/2 = (AB +BD)/2 = (25 +4)/2 = 29/2
r = 14.5
