Well, well, well, aren't we feeling all mathematical today? If one angle is 28 degrees in a right triangle, the other acute angle must be 62 degrees (90 - 28 = 62). As for the right angle, it's a whopping 90 degrees. Math can be a real trip sometimes, can't it?

In a right triangle, one angle is always 90 degrees. Therefore, if one angle is 28 degrees, the other angle must be 90 - 28 = 62 degrees. The sum of the three angles in any triangle is always 180 degrees, so the third angle in this right triangle would be 180 - 90 - 28 = 62 degrees as well. So, the other two angles in the right triangle with a 28-degree angle are both 62 degrees.
The sum of the internal angles of a triangle is 180 degrees. Since you know this is a right-angled triangle, you know that one side is 90 degrees. If the other angle is 28 degrees, then you know that the remaining angle must be 180 - 90 - 28 = 62 degrees.
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
The other acute angle in that triangle is 40 degrees.
Each angles of an equilateral triangle has 60 internal degrees.
