Answer:
Parallel cut-rectangle
Perpendicular cut-triangle
Step-by-step explanation:
A rectangular pyramid has a base that is a rectangle, but comes up into a point.
For this, we use the Pythagorean Theorem to calculate for the side length of the triangle. This can only be used given your triangle is a right triangle. It is expressed as:
c² = a² + b²
where c is the hypotenuse.
c² = 3² + 3²
c = 3√2
Therefore, the perimeter is,
P = 3 + 3 + 3√2 = 6 + 3√2 ----------> Second option
what is the height of it
and what do you want me to find?
Answer:
yes
Step-by-step explanation:
Answer:
To find the point of intersection, you have to set both equations equal to each other and solve. After solving, plug it back into one of the equations. (Its pretty simple so don't worry :] )
y1 = 2x + 4
y2 = 3x-9
y1 = y2
2x + 4 = 3x - 9
4 = x - 9
x = 13
--> Plug x back into an equation for y coordinate. I will be using y1.
2(13) + 4
26 + 4 = 30
y = 30
The point of intersection is (13,30)
