Answer:
8
Step-by-step explanation:
3v-9=7+2v-v
3v-9=7+v
3v-v-9=7
2v-9=7
2v=7+9
2v=16
v=16/2
v=8

Answer:
B. An obtuse scalene triangle
Step-by-step explanation:
Polygons are plane figures bounded by three or more straight sides. Examples are: trigon, quadragon, hexagon, nonagon etc. They are named with respect to their number of sides.
An obtuse triangle has one of its angles greater than
but less than
. While a scalene triangles has non of its sides to be equal in length.
The valid description of the classes of polygons is: an obtuse scalene triangle. Which implies that the triangle has one of its angles to be obtuse, and non of its sides equal.
It would be very likely that it would land heads up, about 100 times. its a 50/50 chance
