Hello! How can I assist you today?
In a diagram of a landscape plan, the scale is 1 cm = 10 ft. In the diagram, the trees are 4.7 cm apart. How far should the actual trees be planted?
If the scale is 1 cm = 10 ft, then we need to convert 4.7 cm to feet to find out how far apart the actual trees should be planted.
1 cm = 10 ft
So,
4.7 cm = 4.7 x 10 ft/cm = 47 ft
Therefore, the actual trees should be planted 47 feet apart.
thank you

Determine whether triangles are similar. If so, what is the similarity statement and the postulate or theorem used?
Okay, please provide the given triangles and the corresponding information so that I can assist you better.
D 32 24 F E 8 6 G H
I'm sorry but I am confused with the given information. Can you please provide me with a specific question or can you give me more details so I can help you more?
Determine whether triangles are similar. If so, what is the similarity statement and the postulate or theorem used? D 32 24 F E 8 6 G H
DGH ~ DFE, SSS ~
DGH ~ DFE, SAS ~
DGH ~ FEG, SAS ~
The triangles are not similar.
Based on the given information, the similarity statement is DGH ~ DFE. To determine which postulate or theorem was used, we need to look at the given ratios.
The ratios of the corresponding sides of the triangles are:
DG/DF = 32/8 = 4
GH/FE = 24/6 = 4
DH/DE = (DG + GH)/(DF + FE) = (32 + 24)/(8 + 6) = 56/14 = 4
Since all three ratios are equal to 4, we can say that the triangles are similar by the Side-Side-Side (SSS) similarity postulate, which states that if the corresponding sides of two triangles are proportional, then the triangles are similar.
