Answer:
b = 8√3 and c = 16 
Step-by-step explanation:
<u>Points to remember</u>
If the angles of a right angled triangle with angles are 30°, 60, and 90 the their sides are in the ratio 1 : √3 : 2
<u>To find the unknown side lengths</u>
From the given figure we can see a right angled triangle
Angles are 30°, 60° and 90°
sides are in the ratio 1 : √3 : 2
1 : √3 : 2 = 8 : b : c
 b = 8√3 and c = 8 * 2 = 16
Therefore b = 8√3 and c = 16

The formula to solve for thee area of a square pyramid is [ V = 1/3 * b² * h ]
b² = base area (b = length of one side of the base)
h = height
The only option that as a base length of 12cm. and a height of 14cm. is the first option.
Solve for the volume if needed.
V = 1/3(12²)(14)
V = 1/3(144)(14)
V = 1/3(2,016)
V = 672cm²
Best of Luck!
 
        
                    
             
        
        
        
Answer:
13. 
parallel: y = 1/3x -3
perpendicular: y = -3x - 3
14.
parallel: y = 4x - 1/2
perpendicular: y = -1/4x - 1/2
15.
parallel: y = -2x + 4
perpendicular: y= 1/2x + 4
16.
parallel: y = -2x-2
perpendicular: y= 1/2x-2
17. 
parallel: y = -2x+8
perpendicular: y= 1/2x + 8
Step-by-step explanation:
A perpendicular has a negative reciprocal slope and a parallel has the same slope
