The sum of two exterior angles of an isosceles triangle is equal to 240°. what are the measures of the interior angles?

Let the two equal interior angles of the isosceles triangle be x and x.

Then, the corresponding exterior angles are 180 - x and 180 - x.

It is given that the sum of the exterior angles is 240°.

Therefore, (180 - x) + (180 - x) = 240

360 - 2x = 240

360 - 240 = 2x

2x = 120

x = 60°

Hence, the measures of each interior angles is 60°.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
