Question: 90


e + c = 90°
Column AColumn B
b + a + d + f270
  • A. if the quantity in Column A is greater
  • B. if the quantity in Column B is greater
  • C. if the quantities are equal
  • D. if the relationship cannot be determined from the information given

Correct Answer: C

Explanation:

The correct answer is (C). The sum of the angles of a triangle equals 180°.

a + b + c = 180

and d + e + f = 180

a + b + c + d + e + f = 360

also e + c = 90

Therefore, a + b + d + f = 270 (subtraction)

Column A = Column B
