**In the diagram above, L1 is parallel to L2** **Find the value of <PMT**

**A. 36°**

**B.** **72°**

**C.** **82°**

**D.** **118°**

**QUICK ANSWER…**

**C**

**SOLUTION****… **** **

**The sum of total angles on a straight line = 180 degrees.**

**From the diagram, 62 + (2y + 10) + y = 180**

**62 + 2y + 10 + y = 180**

**3y + 72 = 180**

**3y = 180 – 72**

**3y = 108**

**Therefore, y = 108/3 = 36 degrees**

**Therefore, angle PMT = 2y + 10 = 2(36) + 10 = 72 + 10 = 82 degrees**

**Now for the right answer to the above question:**

**Option A is incorrect.****Option B is incorrect.****C is correct.****D is not the correct answer.**
