Hi;

It is no trouble for me at all. I like solving problems. But I hope you are trying to solve them too.

hi cooljackiec

The exterior angles of any polygon add up to 360.

3+4+5=12

360/12 = 30

so exteriors are 90:120:150

Thanks, i get it now.

What is the measure (in degrees) of the smallest interior angle of a triangle in which the exterior angle measures have the ratio 3:4:5?

hlep!


One interior angle of a triangle has a measure that is equal to the sum of the measures of the other two angles of the triangle. What is the measure of the smallest exterior angle of the triangle in degrees?
