Answer 2

Answer:

90°

Step-by-step explanation:

let the angle 1 be 1x

angle 2 be 2x

nd,

angle 3 be 3x

now,

1x+2x+ 3x= 180°

6x= 180°

x= 180/6= 30°

hence,

angle 1= 30°,

angle 2= 2× 30= 60°

nd,

angle 3= 3× 30= 90°

now,

angle 3 and angle 4= 180°

but angle 3 is = 90° ( given)

so,

angle 4+ 90° = 180°

angle 4 = 180- 90= 90°
