Question

cab any one can solve this ​

Answer 1

i. ) x = 60°

ii. ) y = 80°

Step by step explanation :

We know that sum of all interior angles of a triangle is equal to 180° .

i ) => Given angles = 90° and 30°

=> 90° +30° + x = 180°

=> 120° + x = 180°

=> x = 180° - 120°

=> x = 60°

ii. ) => Given angles = 80° and 20°

=> 80° + 20° + y = 180°

=> 100° + y = 180°

=> y = 180° - 100°

=> y = 80°
