Question

09. In the given figure, AB II CD and EF is the transversal. Find angle y
​

Answer 1

Answer:

y = 146°

Step-by-step explanation:

2x = 5x - 51

5x - 2x = 51

3x = 51

x = 51/3 = 17°

(5x - 51) + y = 180

85 - 51 + y = 180

y = 180 - 34 = 146°

Answer 2

Answer:

146 degress

Step-by-step explanation:

2x = 5x - 51. [Corresponding Angles]

2x - 5x = -51

-3x = -51

x =

$\frac{ - 51}{ - 3}$

x = 17

5x - 51 = (5 X 17) - 51

= 85 - 51

= 34 degrees

180 degrees = 34 + y. [Supplementary Angles]

180 - 34 = y

180 - 34 = y = 146 degrees
