Question

solve ans please fast if you give correct answer of both I will make you brainlist & thanks all ans​

Answer 1

Answer:

1)  x + 3x = 120

  4x = 120

   x = 30

other number is 3 times the other. so 30 x 3 = 90

90+30=120, answer is right, verified.

2) x-y = 30

other angle = 40

x = y + 30

by angle sum property, y + 30 + y + 40 = 180

2y + 70 = 180

2y = 110

y = 55

so angles are 40, 55, 85.

hope it helped!

Answer 2

Answer:

1) First no.= x = 30

Second no.= 3x = 90

2) x= 55°

y= 85°

Step-by-step explanation:

1) Let the first no. be x.

So, second no. is 3x.

x+3x=120

4x=120

x=120/4

x=30

3x= 30×3=90

2) Let x be x and y be (x+30)°

x+(x+30)°+40°=180°

2x+70°=180°

2x=180°-70°

2x=110°

x=110/2°

x=55°

y=(x+30)°= (55+30)°= 85°
