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°

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
