Answer:
Step-by-step explanation:
Rectangular prisms have F=6 faces and E=12 edges.
By cutting one corner, we are adding 3 edges.
By cutting two corners, we are adding 2*3 = 6 edges.
Therefore the new solid has 12 + 6 = 18 edges.
Answer:
n = - 
Step-by-step explanation:
Given
2nq = 3 + 7nq ( subtract 7nq from both sides )
- 5nq = 3 ( divide both sides by the multiplier - 5q )
n = 
= -
Answer:
The angles are 22.5 and 67.5.
Step-by-step explanation:
A complement is the angle that when added to the given angle gives 90 degrees.
Therefore, the angle x is 3 times larger than its complement.
This means that x is 3/4 of 90 degrees and complement is 1/4 of 90 degrees.
Therefore, the angles are 22.5 and 67.5.
Okay add 78 and 66. Then add 96 and 108. It should be 144 by 204. I know math is hard, but when you work at it you can do amazing things! I hope that helps you.
