Answer 2

$\huge{\underline{\mathtt{\blue{A}\red{N}\pink{S}\green{W}\purple{E}\orange{R}}}}$

Step-by-step explanation:

(ii)=We know the sum of angle of triangle is 180°

So,=2x+6x+x=180°

9x=180°

x=180/9

x=20

So,2x=2×20=40

6x=6×20=120

x=20

(iii)We know the sum of angle of triangle is 180°

So,3x+2x+90°=180°

5x+90°=180°

5x=180°-90°

5x=90°

x=90/5

x=18

3x=3×18=54°

2x=2×18=36°
