Step-by-step explanation:
we know that
The scale factor is![\frac{1.5}{2}\ \frac{in}{mi}](/tpl/images/0475/3231/c75cb.png)
That means
1.5 inches on a map represents 2 miles in actual
To convert the dimension on the map to real dimensions, divide by the scale factor
so
Convert to mixed number
Ответ:
if A , O and B lie on a straight line segment
then
∡AOY+∡YOZ+∡ZOB=180°
so
3x+x+x=180> 5x=180> x=180/5> x=36°
the answer is
x=36°
