Option B is correct
because in a triangle the sum of the 2 sides must be greater than third side but in option B
12cm = 7cm+5cm
12cm = 12cm
hence it cannot form a triangle.
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
The number of cubes is 27
the volume is 36 centimeters cubed
Step-by-step explanation:
-9x + 1 = -x + 17
collect like terms
-9x + x = 17-1
-8x = 16
divide both sides by -8
-8x/-8 = 16/8
x = 2
