not sure if the answer can be left that way or do you assume that test results are whole numbers, if so then the answer would b=have to be 28.. but I think that >27 is the answer expected

an isosceles triangle contains two equal angles. Each of these angles is 25 degrees larger than twice the smallest angle. What a

Helga [31]

Well, the sum of all internal angles in a triangle, isosceles or whatever else, is always 180°, so the sum of all those three folks, will be 180 then

so.. hmmm let's say the smallest angle is "a" units

twice that is, 2*a, or 2a
25 larger than that? is well 2a + 25

so... the other two twin angles, are 2a+25 each

thus a + (2a + 25) + (2a + 25) = 180

solve for "a" to find the smalles one

what about the twins? well, each is 2a + 25
