The figure above shows a construction plan for the intersection of three straight roads, each having parallel edges and each having the same width. What is the value of t? I. r = 140 II. s = 160
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
EACH statement ALONE is sufficient to answer the question asked.
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
Option C is the correct answer.
Statement I is insufficient: r = 140. Not sufficient.
Statement II is insufficient: s = 160. Not sufficient. Together I and II, Consider the width of the roads to be 0 as shown below:
From the figure we have that r+s+t=360 degrees –> 140+160+t=360 –> t=60 degrees. Sufficient.
