Which of the following can be used to construct a triangle? A) 30 40 90 degrees
B) 120 52 98 degrees
C) 100 25 55 degrees
D) 80 80 80 degrees

9514 1404 393

  C)  100 25 55 degrees

Step-by-step explanation:

The sum of the angle measures must be 180°.

  A: 30 +40 +90 = 160

  B: 120 +52 +98 = 270

  C: 100 +25 +55 = 180 . . . . these form a triangle

  D: 80 +80 +80 = 240

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
