Find the apothem of an equilateral triangle with radius 8 cm.

In this question , the triangle is equilateral triangle , with radius equals to 8 cm  and we have to find the length of apotherm, a .

Using sine ratio rule,

For triangle ODC, opposite is a cm and hypotenuse is of length 8 cm .

So we will get

Multiplying both sides by 8

So the length of the apothem is 4 cm .

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
