An equilateral triangle.
An obtuse triangle has one angle greater than 90 degrees.
The third angle is 180-(60+70) = (180 - 130) = 50degrees.-- All of its angles aren't equal, so it's not an equilateral triangle.-- No two of its angles are equal, so it's not an isosceles triangle.-- No angle in it is 90 degrees, so it's not a right triangle.-- No angle in it is greater than 90 degrees, so it's not an obtuse triangle.--> It's an acute, scalene triangle.
An equilateral triangle has 3 interior equal acute angles each measuring 60 degrees. In general an acute angle is greater than 0 but less than 90 degrees.
The three angles are 40, 50 and 90 degrees.
