Answer:
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.
We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
An integer is a whole number, in other words, a number that isn't a fraction or decimal.
0 + 0 + -2 + -2 + 2 + -2 = -4
-4 is an integer because it is not a fraction or decimal.
Best of Luck!
