Answer:
I would say that by the 20th figure, there would be more than 400 small triangles by the 20th figure.
Step-by-step explanation:
Based on figure 1 and 2, I'm guessing the ratio is 2.
Figure 4: 32
Figure 5: 64
Figure 6: 128
Figure 7: 256
Figure 8: 512
Figure 9: 1,024
Answer:
they are equal to each other
Step-by-step explanation:
no because 2/3 is a simplified version of 4/6, so they are equal
Answer:
x=8 y=4
Step-by-step explanation:
x=12-y
12-y-y=4
-2y=-8
y=4
x=12-y
x=12-4
x=8
Answer:
b = 22 m
Step-by-step explanation:
The formula for calculating the area (A) of a triangle is
A = 
bh
multiply both sides by 2 to eliminate the fraction
2A = bh ( divide both sides by h )
b = 
, hence
b = 
= 
= 22 m
Answer:
See below.
Step-by-step explanation:
Recall that the biggest angle will always be opposite from the biggest side.
IT is opposite from Angle S, which we can figure out to be 180-108-25=47.
SI is opposite from Angle T, which is 41.
ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.
The smallest side is SI, then IT, then ST.
The correct order is: SI, IT, and ST.
