That's true. The definition of an isosceles triangle is that it has at least 2 sides equal in length. Therefore, isosceles can be equilateral, but equilateral cannot be isosceles.
Answer:
- radius: 15 ft
- diameter: 30 ft
- circumference: 30π ft
Step-by-step explanation:
The area is given in terms of the radius as ...
A = πr^2
so we can find the radius as ...
r = √(A/π)
For your circle, the radius is ...
r = √(225π ft^2/π) = 15 ft
The diameter is twice the radius, so is ...
d = 2r = 2·15 ft = 30 ft
And the circumference is π times the diameter:
C = πd = π·30 ft = 30π ft
There's no problem so we can't answer it

31.12 in
<u>Explanation
</u>
To get the length required, lets first find angle mF,
mF = 180 – (43 + 62) =75o
Now we can use the sin rule to find length DE.
a/sinA =b/sinB Where a and b are the length opposite to angle A and B respectively.
DE/sin75=22/sin43
DE=(22 sin75)/sin43
DE=31.12 in
