Answer: An estimate done quickly: The circumference is about 75 ft.
Step-by-step explanation:
Round π to 3, and 24 to 25. 3 times 25 is 75
A more exact value would be 75.36
3.14 × 24 = 75.36
Answer:
6√3 = x y =12
Step-by-step explanation:
Since the two sides of the triangles have equal angles then two sides have equal length
the sum of interior angles of triangles is 180° then the last angle is 60°
then the triangles have perfect sides of 12
y = 12
to calculate x
sin Ф = opposite/hypothenus
sin 60° = x/12
sin 60° = √3/2
( √3/2 ) x 12 = x
6√3 = x
Im a little confused here because there isn't enough information to go on or I might be reading it wrong.
