**From the diagram above PQ||RS and <PTR = 37ᵒ. What is the value of x?**

**A. 127ᵒ****B. 37ᵒ****C. 53ᵒ****D. 90ᵒ**

**QUICK ANSWER…**

**C**

**SOLUTION****… **** **

**If PQ is parallel to RS, then <PTR = <TRS = ****37**

**But from the diagram, <RTS = 90,**

**If the sum of total angles in a triangle = 180, then:**

**37 + 90 + x = 180**

**x = 180 – 37 – 90 = 53 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.**

**KEY-POINTS…**

**You may please note the****se/this****:**

**Sum of total angles in a triangle = 180 degrees****Sum of total angles in a straight line = 180 degrees****Opposite angles on a line joining parallel lines are equal.**
