An equilateral triangle has an apothem of 5cm. Find the perimeter of the triangle to the nearest centimeter

Sloan [31]

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.

Find the coordinates of the midpoint of the segment whose endpoints are h(6,4) and k(2,8)

ozzi

Answer:

$(4,6)$

Step-by-step explanation:

we know that

The formula to calculate the coordinates of the midpoint between two points is equal to

$M(\frac{x1+x2}{2},\frac{y1+y2}{2})$

we have that

The coordinates of hk

$h(6,4), k(2,8)$

substitute in the formula to calculate the midpoint

$M(\frac{6+2}{2},\frac{4+8}{2})$

$M(\frac{8}{2},\frac{12}{2})$

$M(4,6)$
