Question

Find the unknown angles in the given triangle​

Answer 1

Step-by-step explanation:

We know that sum of all angles of triangle is 180°

So,

80°+ x°+ y° = 180°

x + y = 180 - 80

x + y = 100

So x= 50

and y= 50

Answer 2

Answer:

x = y = 50°

Step-by-step explanation:

80° + x + y = 180°

x + y = 180° - 80° = 100°

x = y = 100/2 = 50°
