The photo shows a small coin. The scale from the actual coin to the photo is 8 mm to 2 cm In the photo, the distance across the coin is 3.25 cm what is the distance across the actual coin? 

1.3cm

Step-by-step explanation:

The scale from the actual coin to the photo is 8 mm to 2 cm In the photo,

converting 8mm to cm = 0.8 cm

using ratio and proportion,

if 2cm = 3.25 cm

then 0.8cm = ? less

if less then more devides.

thus ; (0.8cm ÷2cm ) × 3.25cm =

( 0.4) × 3.25cm = 1.3cm

therefore the distance across the actual coin is 1.3cm.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
