Question

10.
Find the value
120°
of x and y from the figure.
(3y+6)°​

Answer 1

Answer:

x=60, y=18

Step-by-step explanation:

Given: Three angles: 120 °, x ° and (3y + 6) º To find: The value of x and y? Solution: Now we have given three angles and the arrows show that the lines are parallel. Now: 120 + x = 180 ................. (linear pair as both the lines are parallel) x = 60 degree. . Now: x = 3y + 6 (similar angles as the lines are parallel) 60 = 3y + 6 54 = 3y y = 54/3, x = 60 degree. . Now: ............ x = 3y + 6 (corresponding angles as the lines are parallel) 60 = 3y + 6 54 = 3y y = 54/3 y = 18
