Answer:

x=31

y=64

Step-by-step explanation:

the angle with the double mark is 85° so the angle on the same line which is marked (x) is 31°

since sum of angles in a triangle is 180° , therefore, y= 180-85-31 which is 64°

Because these two triangles are congruent, and the sum of ALL angles are 180°

So,
x = 31° ( as shown in the picture) —————————

So really you should be solving for y.

85° + 31° + y = 180°

116° + y = 180°

y = 64° ——————————
