In the figure above, x =

(A) 30

(B) 35

(C) 60

(D) 75

(E) 150

Attachment:
#GREpracticequestion In the figure above, x =.png

Key Concept: Angles on a line add to 180°
So, we can write: 30° + x° + x° = 180
Simplify: 30° + 2x° = 180
Subtract 30° from both sides: 2x° = 150°
Divide both sides by 3 to get: x° = 75°

Answer: D

Problem Solving
Figures: All figures accompanying problem solving questions are intended to provide information useful in solving the problems. Figures are drawn as accurately as possible. Exceptions will be clearly noted. Lines shown as straight are straight, and lines that appear jagged are also straight. he positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero. All figures lie in a plane unless otherwise indicated.

Data Sufficiency:
Figures:
• Figures conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).
• Lines shown as straight are straight, and lines that appear jagged are also straight.
• The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero.
• All figures lie in a plane unless otherwise indicated.

A straight angle has 180 degrees. Thus, we can create the equation:

30 + x + x = 180

2x = 150

x = 75
