Answer 2

Step-by-step explanation:

PQ is a straight line.

Then, ∠POR + ∠ROT + ∠TOQ = 180

Given, x : y = 3 : 2 Let us assume x = 3a, y = 2a 90o + 3a + 2a = 180

90o + 5a = 180o

5a = 180o – 90

5a = 90o

a = 90/5

a = 18

So, x = 3a = 3 × 18 = 54 Y = 2a = 2 × 18 = 36

From the figure SOT is a straight line, Then, Z + Y = 180 Z + 36 = 180 Z = 180o – 36o Z = 144o
