As per the question, the triangle is right angle triangle, so
angle 1 = 90 degree...........(1)
also sum of two angle = 120 degree
since given triangle is a right angle triangle, then sum of two angle can become 120,
only if one of the angle is 90 degree.
so the equation we get;
90+ angle 2 = 120
divide both side by 90 and we get,
angle 2 = 30 degree................... (2)
By angle sum property of triangle,
sum of all the angle of triangle = 180...........(3)
put the value from (1) (2) into (3) and we get;
90 + 30 + angle 3 = 180
120 + angle 3 = 180
divide both side by 120 and we get;
angle 3 = 60 degree
Hope this will help you |
