Question

in the figure l1 parallel to l2 and l2 parallel to l3 . AB perpendicular to l1 and angleCBF = 55 degree .find the value of x y and z​

Answer 1

Answer:

x = 125°

y = 125°

z = 35°

Step-by-step explanation:

In the given figure,

AB is perpendicular to l1, l2, and l3

So, on l3, 55° + z = 90°

z = 90° - 55°

z = 35°

Also, angle y and angle EBF are supplementary angles [co-interior angles]

Therefore, y + 55° = 180°

y = 180° - 55°

y = 125°

Now, y = x [Corresponding angles]

x = 125°
