Answer:
In the case of the equilateral triangle, , the exterior angle, plus 60 equals 180. Subtracting 60 from both sides of this equation gives us a value of equal to 120. This means that the exterior angle of an equilateral triangle is equal to 120 degrees. The sum of all the exterior angles is always 360 degrees.
Step-by-step explanation:
Answer:
<em>1.3%</em>
When entered into a calculator, 12/890 (the chance of a given calculator being defective) = 0.01348...
As a percent this is 100*0.01348% = 1.348%, and to the nearest tenth, 1.3%
