1=y=60,x=70

2.y=50,x=80

3.y=70,x=120

4.y=110,x=60

5.y=90,x=45

6.x=60

Step-by-step explanation:

it took a lot of time to write this pls make me brainliest

Answer 2

(I). y +120°=180

y=180°-120°

y=60°

to find x

120° +50°+x=180°

170°+x=180°

x=180°-170°

x=10°

(ii) .80°=x (because of opposite side)

to find y

80°+50°+y=180°

130°+y=180°

y=180°-130°

y=50°

(iii) . 50°+60°+y=180°

110°+y=180°

y=180°-110°

y=70°

to find x

70°+x=180°(linear pair)

x=180°-70°

x=110°

(iv) .x=60°(opposite side)

to find y

60°+30°+y=180°

90°+y=180°

y=180°-90°

y=90°
