A right triangle has its other two angle measurements given in ratios 2:3 relative to each other. What is the measurement of one of the other two angles?  Choices
A) 36Â°	B) 45Â°	C) 60Â°	D) 74Â°	E) 86Â°
A right triangle has a 90Â° angle, so the other two angles should add up to 90Â°. With the 2:3 ratio, we use the equation   2x + 3x = 90Â°   5x = 90Â°   x = 18Â°   2x = 36Â°, which is 36Â°   3x = 54Â°, which is not in the choices, so the answer is 36Â°
