Sample Test Item 42 (2003)
Posted on December 11th, 2007 by admin
This question is testing your knowledge of congruent angles of an isosceles triangle.
After this is recognized, the rest is just alegbra. That is,
(1/2)x - 59 = -3x - 31
Combining like terms, we add 3x from both sides. We add 59 to both sides. We have
(3+ (1/2))x = -31 + 59
(7/2)x = 28
x = 8.
The answer is Choice A.
