The figure shows three exterior angles of triangle abc. show that the measure of angle 1 plus the measure of angle 2 plus the measure of angle 3 equals 360

Step-by-step explanation:

Let the angle near point A be .

Let the angle near point B be .

Let the angle near point C be .

Let the external angle near point A be .

Let the external angle near point B be .

Let the external angle near point C be .

According to exterior angle property,exterior angle of an angle is the sum of other two angles.

So,

According to angle sum property,the sum of angles in the triangle add to

- 70

this is the answer for you hope it

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"
