Answer:
3. ΔBEA ~ ΔBCD by AA
4. ΔPXY ~ ΔPQR by SSS
Step-by-step explanation:
3. The missing angle in ΔBEA is angle E, which has measure ...
∠E = 180° -42° -53° = 85°
So, angle E matches angle C, and the vertical angles match. The two triangles are similar by AA. The corresponding angles are B:B, and E:C, so the similarity statement needs to reflect that: ΔBEA ~ ΔBCD.
__
4. Shortest-to-longest, the side ratios of the two triangles are ...
12 : 15 : 18 = 4 : 5 : 6
and
16 : 20 : 24 = 4 : 5 : 6
Side ratios are proportional, so the triangles are similar by SSS. The similarity statement can reflect the same ordering: ΔPXY ~ ΔPQR.
The volume of a box is the product of its dimensions
The volume of the box is 11 unit cube
<h3>How to determine the volume</h3>
From the question, we have the following highlights
- The cubes are unit cubes
- The boxes are packed without gaps
The volume of a unit cube is:
Volume = 1 unit cube
There are 11 cubes in the box. So, the volume of the box is:
Volume = 11 *1 unit cube
Volume = 11 unit cube
Hence, the volume of the box is 11 unit cube
