The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
tan 30° = apothem / 0.5(length of side)
Substituting the known values,
tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B.
Answer:
14/27 square yards
Step-by-step explanation:
2/3 times 7/9 gives you 14/27
2x - 3y = 8....subtract 2x from both sides
-3y = -2x + 8 ...divide both sides by -3
y = 2/3x - 8/3
To solve that use the Quadratic formula.
