The angles in a triangle always add up to exactly 180 degrees. To see if this can be a triangle, add up the given angle measures. If the sum is not 180, then it cannot be a triangle.
140+43+7=190
A triangle CANNOT have the angles measures as 140, 43, and 7.
Hope this helps!!
Answer:
C
Step-by-step explanation:
A relation is a function if each input gives exactly one output. There is one price for each number of pounds, so the relation is a function.

<em>Additional comment</em>
Relations expressed in terms of ordered pairs or tables can be identified as "not a function" if any input (x) value is repeated. Relations expressed as a graph will be "not a function" if any vertical line intersects the graph at more than one point. (This is called "the vertical line test.")
The cost function in this case is a straight line through the origin. It has a slope of $5.99/lb. Any polynomial relation will be a function.
Answer:
(a) 
(b) 
Step-by-step explanation:
(a) 
can also be written as 
x 
the = ± y
Therefore :
= ±
since it was given that y < 0 , then the factor will be
(b) 
can also be written as : 
x
Therefore , one of the factor is
Answer:
a,d,c
Step-by-step explanation:
The obtuse interior angle in triangle can reach to 179.9999999.... °.
Because once it hits 180°, the angle becomes a straight line and it is not possible in a triangle.
