Answer:
x=8
Explanation:
The picture tells us that the triangle is equilateral (this means that each angle is 60°). We can assume this because each side has been marked with the same line.
Because each angle is equal to 60°, this means that:
7x+4=60
Now solve for x:
7x=56
x=8
X + 2(x + 4) = 32
3x + 8 = 32
3x = 24
x = 8
The lengths of the sides are 8, 12 and 12 (answer),
Plug in m/4 into the equation:

Solve the parentheses in the equation:



Your equation should now look like this:

The answer is
D.
Answer:
the scale factor is 3/4
x = 16×3/4 = 12
Step-by-step explanation:
the only side length we have for both triangles is the short left side.
we see that we get ED from SR and need to transform 4 into 3. how do we do that ?
well,
4×f = 3
f = 3/4
that is the scaling factor, as all side lengths in EDF are created by multiplying the corresponding side in SRT by the same scaling factor (3/4).
therefore,
x = EF = ST×f = 16×3/4 = 4×3 = 12
Answer:
- Perimeter of the original Rectangle is
2(4.5+4.3)=2×8.8= <u>17.6</u><u> </u><u>mm</u>
- Side length of the enlarged rectangle is

- Perimeter of the enlarged rectangle
2(24.3+23.22)= 2×47.52= <u>95.04 mm</u>
