Answer:

  x = 12.5

Step-by-step explanation:

The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you <em>the sum of angles in a triangle is 180°</em>.

This gives you the equation ...

  60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°

  4x +130° = 180° . . . . . . . . . . collect terms

  4x = 50° . . . . . . . . . . . . subtract 130° from both sides

  x = 12.5° . . . . . . . . . divide both sides by 4

Scale on map is Lin 86 mi if actual distance is 35 mi . Between two cities how far apart on the map are they
Mrac [35]

Answer:

0.41 cm

Step-by-step explanation:

The scale on the map is 1 in 86 mi.

This means that, 1 cm on the map represents 86 miles in real life, or on earth.

Then we're told that in real life, a distance is 35 miles, and how far they are on the map.

If 1 cm equals 86 miles, then we can say that x cm equals 35 miles

1 cm ----> 86

x cm ----> 35

x * 86 = 35 * 1

x = 35 / 86

x = 0.41 cm

Therefore, they must be 0.41 cm farther or closer apart on the map scale.
