Question

Help me find XY!!!!!

Answer 1

Answer:

x = 11.428

Step-by-step explanation:

See the diagram of angles attached to this question.

XY is a segment of straight line and straight line n is a transverse and they meet at point M.  

So, the angles formed by the transverse line will be supplementary.

Therefore, from the diagram, (5x + 8) + (9x + 12) = 180°

⇒ 14x + 20 = 180

⇒ 14x = 160

⇒ x = 11.428 (Answer)
