Answer: 5
Step-by-step explanation: These two triangles are similar triangles. Since they are similar, they must be scaled equivalently. The scale factor is 5. To know this, 3 times 5 is 15, and being equivalent, we can figure 5 times 5 is 25. Therefore x is 5. That also means that the scale factor of the smallest triangle to the biggest triangle is 5. Thus, x is 5.
Answer:
35
Step-by-step explanation:
each side is longer by 1 cm and every side has 2 corners so it would be 27+8=35
1 km^2 = 1000m x 1000m = 1 x 10^6 m^2
<span>(145 acres / 247 acres) x 1 x 10^6 m^2 = 5.87 x 10^5 m^2 </span>
<span>5.5 g/m^2 x 5.87 x 10^5 m^2 = 3.23 x 10^6 g </span>
<span>3.23 x 10^6 g x 1kg/10000 g = 3.23 x 10^3 kg</span>
We see that the second definition is not a good definition. We want both parts to have the same truth value, but we see that we can have two angles created by a ray that are not equal. That means the antecedent is false but the consequence is true, which means it's not an iff statement, and a bad definition in this context.
