In the diagram, QR//ST, /PQ/ = /PR/ and In the diagram, QR//ST, /PQ/ = /PR/ and o. Find the value of y A. 105o B. 110o C. 130o D. 150o Correct Answer: Option A Explanation In (bigtriangleup) PQR, Q = S = 75o (Corresponding angle) R = Q = 75o (Base angles of an isosceles (bigtriangleup)) But, y + 75o = 180o (Sum of angles in a straight line) y = 180 – 75 y = 105o `, props: [‘comment’], data() { return {} }, methods: {} }) {{ reply.posted_by.display_name }}: {{ reply.created_at }}
