​

Answer 1

Answer:

a +b+c=180 now a+b =90 putting this in eq. c=90

and a-b=50 by solving this and a+b=90 answer will come

Answer 2

Step-by-step explanation:

Sum of two angles of a triangle is 90°

Then third angle is = 180°-90°=90°

Let two angle is x and y.

=> x + y = 90°-------------1

=> x -y = 50° - - - - - - - - -2

So, add both equations,

=> 2x = 140°

=> x =70°

=> y = 90°-70°=20°

Therefore, the angles of the triangle is 20°;70° and 90°.
