False, an isosceles triangle has 2 equal sides.
Answer:
<BAC = 20°
Step-by-step explanation:
It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.
Which means 9 angles collectively can be written as 9 · <BAC
If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.
A semicircle has a total sum of angles equal to 180°
So we can write that:
9 · <BAC = 180°
Simplify for <BAC
<BAC = 20°

Step-by-step explanation:
The first column has 10 cubes.
The question states that the other two columns each have 4 fewer cubes than the first column.
10 - 4 = 6
This means that each of the other 2 columns have 6 cubes each.
Column 1: 10 Cubic units
Column 2: 6 Cubic units
Column 3: 6 Cubic units
10 + 6 + 6 = 22
Anna’s Figure has 22 Cubic Units
Answer:
4=1
Step-by-step explanation:
2(n + 2) = 4n + 1 - 2n
2n + 4 =4n - 2n + 1
2n + 4 = 2n + 1
<em>add -2n to each side</em>
2n-2n+4=2n-2n+1
0+4=0+1
4=1
idk if this is right myself but this is want i found on internet, i searched it up for 1 hour and this is the ans they gave me...
