Question

Plllllllssss fasssssttttttt guuuuuyyyyssssszs

Answer 1

Answer:

(2x + 4 )° + ( x - 1 )° = 180° ( linear pair )

2x + 4 + x - 1 = 180

2x + x + 4 - 1 = 180

3x + 3 = 180

3 ( x + 1 ) = 180

$(x + 1 )= \frac{180}{3} \\ x + 1 = 60 \\ x = 60 - 1 \\ x = 59$

I hope it will help you

Answer 2

Step-by-step explanation:

(2x+4)+(x-1)=180°

(2x+x)+(4-1)=180°

3x+3=180°

3x=180°-3

3x=177°

x=177°/3

x=59
