Answer:
11 small frames, 5 large frames
Step-by-step explanation:
small: x
large : y
x + y = 16
4x + 14y = 114
Multiply first equation by 4 and subtract.
4x + 4y = 64
-(4x + 14y = 114)
-10y = -50
y = 5
Substitute y into the first equation.
x + 5 = 16
x = 11
Answer:
Step-by-step explanation:
so all the angles of a triangle add up to 180 degrees
180-42-62= 76
so we know angle TUS is 76 degrees
the other triangle has an angle of 78 degrees which isn't 42, 62, or 76.
The triangles are not similar because similar shapes have congruent angles
Answer:
Square cross section (Red)
Step-by-step explanation:
If the pyramid is cut with a plane (green) parallel to the base, the intersection of the pyramid and the plane is a square cross section (red). If the pyramid is cut with a plane (green) passing through the top vertex and perpendicular to the base, the intersection of the pyramid and the plane is a triangular cross section (red)
