An equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees and trisecting a 60 degree angle equally would give 3 equal 20 degree angles.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
90 - 20 = 70 degrees.
70 degrees A right triangle has one angle that HAS to be 90 degrees. If the other is 20 degrees, and all three angles need to add to 180 degrees: 90+20+x=180 x=70
we add the 20 degrees to the 30digrees so it is 50
No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
If that is the angles of a triangle then the 3rd angle is 110 degrees
Any triangle that has an angle measuring 90 degrees is a right triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.

Yes. The angle that is not the same can be 140 degrees. Because the other two angles are equal, then they would both be 20 degrees.
The 3rd angle is 70 degrees which would form a right angle triangle.
A triangle with angles 103 degree, 20 degree, and 57 degree is called
right triangle and the other angle would be 70 degrees. Hope I helped :)
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
Any triangle with a 90 degree angle is classified as a right triangle.
20 degrees
