The answer is C <<<===== It can't be anything else. It is not a right angle. A>90 It can't be acute because one angle is greater than 90. It can't scalene because at least 2 of the angles (and 2 sides) are equal.
A=x B= 2x C=3x If you add them up = 6x =180 ÷6 both sides x=30 A=30 B=60 C=90 one angle is 90 degrees so the triangle is classified as a right triangle
