Question

the angles of triangle are x-60,2x-180,xwhat type of triangle is it ?

Answer 1

The sum of the angles is 180 degrees. So look at
\[(x-60) + (2x-180) + x = 180\]
solve for x, then work out the other 2 angles. Possible answers would be accute, obtuse, right, equilateral, or isosceles.

Answer 2

x - 60 + 2x - 180 + x = 180
4x -240 = 180
4x = 420
x = 105

The angles are 105°, (105 -60) = 45º, and (2*105-180) = 30°.
