A right angle
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
a 60-degree angle
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
a 60 degree angle is twice the size of a 30 degree angle.

A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.

A 60 degree angle
yes
I assume your 90 degree angle is on the right and the 30 degree angle is opposite that. ( degree mode ) sin theta = opposite/hypotenuse sin 30 degrees = opp./44 = 22
If a right angle triangle has an interior angle of 30 degrees then the other two angles must be 90 degrees and 60 degrees.
It is 60 degrees
