A right angle is 90 degrees. One and a half of 90 degrees is 90 + 45 = 135 degrees
Since the angles of a triangle add up to 180°, if one of the angles is a right angle (definition of a right triangle) then the sum of the other two will be 90°. If we designate the measure of the smaller acute angle as "x" then the other angle will be "4x" and: x + 4x = 90° so 5x= 90° and x = 18°
There are: 2.5 times 90 = 225 degrees
15°
