Let the first and second angle be a and b respectively
Third angle = a+b
By angle sum property of triangle
a +b + a+b = 180
=> 2a +2b = 180
=> 2(a+b) = 180
=> a+b = 90°
Third angle = 90°
Third angle = a+b
By angle sum property of triangle
a +b + a+b = 180
=> 2a +2b = 180
=> 2(a+b) = 180
=> a+b = 90°
Third angle = 90°

Answer:
Step-by-step explanation:
Let the two angles be x and y respectively.
It is given that the sum of the two angles is equal to the third angle.
Therefore,
Third Angle = x+y
x+y+y=180
2x+2y=180
x+y=90
There fore the third angle is 90 degrees
