Answer
Find out the altitude of the equilateral triangle .
To proof
By using the trignometric identity.
As shown in the diagram
and putting the values of the angles , base and perpendicular
solving
As
put in the above
a = 4 × 3
a = 12 units
The length of the altitude of the equilateral triangle is 12 units .
Option (F) is correct .
Hence proved
Answer: 2 / 3 = 0.666666666667
Step-by-step explanation:
m< AOC = 90°
m< AOB +m<BOC = 90°
6x-12+3x +30 = 90°
9x +18° = 90°
9x = 90- 18° = 72°
x = 8°
m<AOB =6(8)-12 = 48-12 = 36°
Answer:
Circular one
Step-by-step explanation:
It really depends on how you cut it, but circles are just one big edge that's curved to meet up with itself.
Also, corners aren't edges and rectangles have corners.
Go with the circle one
