Answer:

Step-by-step explanation:

No figure supplied, so lots of assumptions needed.

Assume side length of triangle is 4 cm.

( If = 4 cm means ??)

Assume ABC is equiangular, all three angles are 60 degrees.

(This is a cross-sectional view, but don't see any)

Side length = 4

altitude of triangle = 4 sin(60) = 2sqrt(3)

radius of circumscribed circle of equilateral triangle

R = (2/3) altitude

= (2/3)*2sqrt(3)

= (4/3)sqrt(3)

Diameter

D = 2R

= (8/3) sqrt(3)

Answer: 8 cm

Step-by-step explanation:

The figure in the image attached below shows that there are two specific angles that are congruent to each other, angles AD and CD.

We are given the length of one of these angles:

AD= 4 cm so we must multiply 4 by 2, since there are TWO angles measuring 4 cm.

4 cm x 2 angles (AD and CD) =8 cm.

Proof of answer is shown below!
