$7.5\% \text { of } x = 9 \text { students}$

$0.75 \times x = 9 \text { students}$

$0.75x = 9$

A regular hexagon has an apothem measuring 14 cm and an approximate perimeter of 96 cm.

WINSTONCH [101]

Given:
hexagon
apothem of the hexagon: 14 cm
perimeter of the hexagon: 96 cm

Area of the hexagon = [(3√3) / 2] a² ; where a is the measure of the side

hexagon has 6 sides.

Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a

We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .

Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2
A = 112 cm²

112 cm² * 6 triangles = 672 cm²

The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,

romanna [79]

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

$tan=\frac{opposite side}{adjacent}$
