WebAll triangles have internal angles that add up to 180°, no matter the type of triangle. An isosceles triangle will have two angles the same size. In an equilateral triangle, all … Weblet a be the largest angle and b, c be the smaller two angles, and a + b + c = 180. a - 25 = c. b + c = a + 30. Notice that b + c = 180 - a. You can now rewrite the second equation by substituting b + c with 180 - a so that you only have to deal with 1 unknown term: 180 - a = a + 30. Rearrange the terms you get:
