Question

in the given figure xoy is a line find the value of angle xoz and angle zoy​

Answer 1

xoz + zoy = 180 (linear pair

2y+12+4y+18=180

6y+30=180

6y=180-30

6y= 150

y=150/6

y= 50/2=25

xoz = 2y+12

2×25+12=62°

zoy= 4y+18

4×25+18

100+18=118°

please follow me

Answer 2

Step-by-step explanation:

(2y+12)+(4y+18)= 180° (Linear Pair)

6y+30= 180°

6y= 180-30= 150

y= 150/6

So, 2y+12= 2(150/6)+12= 62°

4y+18= 4(150/6)+18= 118°
