find the value of (x+y)
215°
70°
135°
145°
Correct answer is A
sum of angle in a straight line = 180°
35 + m = 180
m = 180 - 35 = 145°
Corresponding angles are congruent i.e equal to each other
Angle X and M are congruent = 145
sum of angle in a straight line = 180°
110 + n = 180
m = 180 - 110 = 70°
Angle Y and N are congruent = 70°
∴∴ ( x + y) = ( 145 + 70)°
(x + y) = 215°
