plz don't spam​

Answer 1

Step-by-step explanation:

line EA =180°

therefore

(x+30)°+(x+21)+(x)=180

3x + 51 = 180

3x=180-51

3x = 129

x= 129/ 3

x= 43

Answer 2

Answer:

this is a linear pair and measure of linear pair is 180°

(x+30) ° + ( x+21) ° + x = 180°

3x + 51 = 180°

3x = 180 - 51

3x = 129

x = 129/3

x = 43°

so the angles are :-

x = 43°

(x+30) ° = 43+30 => 73°

(x+21) ° = 43 + 21 => 64°
