Answer:
   250 cm²
Step-by-step explanation:
The lateral area is the total area of the 5 rectangular faces. Each is ...
   A = LW = (10 cm)(5 cm) = 50 cm²
The lateral surface area is ...
   LSA = 5 × 50 cm² = 250 cm²
 
        
             
        
        
        
Answer:
This would be neither as they're passing through points that are across from each other by a large distance.
 
        
             
        
        
        
Answer: 5/3
One of the side lengths goes from 3 to 5. So, the scale factor is 5/3.
Hope that helped!

Answer:
similar; RYL by SAS similarity
Step-by-step explanation:
Side RL Is congruent to side RH and side RY is congruent to side RA by a scale factor of 3.5. and we know thank angles LRY and HRA are congruent by the reflexive property. So the two triangles are congruent by Side-Angle-Side similarity.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n 
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n 
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x =
