Question

Pls solve with steps

Answer 1

Step-by-step explanation:

(i) 40+x+25=180 (linear pair)

65+x=180

x=180-65

x=115

(ii) x+25=y (vertically opposite angle)

115+25=y

y=140

(iii) z=40 (vertically opposite angle)

Answer 2

Answer:

x=115°

y=140°

z=40°

Step-by-step explanation:

40°+x+25°=180°( As we know this addition give us 180°)

Hence,

40°+x+25°=180°

x+65°=180°

x=180°-65°

x=115°

So, x = 115°

Again,

40°+y=180°

y= 180°-40°

y= 140°

So, y = 140°

Again,

115°+25°+z =180°

z+140°=180°

z=180°-140°

z=40 °

So, z=40°
