Answer:

a) x=180-62= 118°

b) x=59°

2x+1+x+2=180°

3x+3=180°

3x=180-3

3x=177

x=177/3

x=59°

c) x+2x+3x+4x=180°

10x=180

x=180/1

x=18°

d) 3x+10+2x-40=180°

5x-30=180°

5x=180+30

5x=210

x=210/5

x=43°

e) x+35+125+72=360

Answer 2

Answer:

Step-by-step explanation:

1 . line AB is a straight line

means it is of 180°

so  62° + x° = 180°

x° = 180 - 62 ° = 118 °

2 . it is also a straight line so the sum of the angles will be 180°

2x+1 ° + x+2° = 180°

3x + 3 = 180°

3x = 180 - 3

3x = 177

x = 177/3

x = 59°

now put the value of x in angles

2x + 1° = 2×59+1 = 119°

x + 2 °= 59 + 2 = 61°

3.  now the sum of all angles are 180 °

x + 2x+3x+4x = 180 °

10x = 180°

x = 18°

so angle x = 18°

              2x = 36°

              3x = 54°

              4x = 72°

4 . the sum of all angles is 180 °

3x + 10  + 2x - 40 = 180°

5x - 30 = 180°

5x = 210°

x = 42°

put x in these angles

3x + 10 = 3×42+10 = 136°

2x - 40 = 2×42 - 40 = 44°

5. now here the sum of all angles is 360°

35 + 125+72 + x = 360°

232 + x = 360°

x = 360 - 232

x = 128°
