11. The two angles are vertical angles, which mean they are equal to each other.
14x - 5 = 13x
Add 5 to both sides:
14x = 13x + 5
Subtract 13x from both sides:
x = 5
12.  The two angles are supplementary and when added together need to equal 180 degrees.
5x -20 + 3x = 180
Combine like terms:
8x -20 = 180
Add 20 to both sides:
8x = 200
Divide both sides by 8:
x = 200 /8
x = 25
 
        
             
        
        
        
Answer:
what your question is but it travels 67 miles in an hour 
Step-by-step explanation:
take 268 divide by 4 you get 67 
 
        
             
        
        
        
To find the surface area you will find the area of each flat surface or each face.
 The faces are in the shape of a rectangle , so multiply the length by the width.
A = lw
Front/ Back-3 1/2 x 3 1/3 = 11 2/3 ft.² 
Sides- 3 1/3 x 3 1/3 = 11 1/9 ft.²
Top/bottom - 3 1/2 x 3 1/3= 11 2/3 ft.² 
Add together to get the total surface area.
 11 1/9+11 1/9+11 2/3+11 2/3+11 2/3+11 2/3 = 68 8/9 ft.² 
 The total surface area is 68 8/9 ft.².

Answer:
The angle it turns through if it  sweeps an area of 48 cm²   is   448.8°
Step-by-step explanation:
If the length of a minute hand of a clock is 3.5cm, to find the angle it turns through if it  sweeps an area of 48 cm, we will follow the steps below;
area of a sector = Ф/360  ×   πr²
where Ф is the angle,  r is the radius   π is a constant
from the question given, the length of the minute hand is 3.5 cm, this implies that radius r = 3.5
Ф =?   area  of the sector= 48 cm²    π = 
we can now go ahead to substitute the values into the formula  and solve Ф
area of a sector = Ф/360  ×   πr²
48   =  Ф/360  ×   × (3.5)²
 × (3.5)²
48 = Ф/360  ×   ×12.25
 ×12.25
48 = 269.5Ф / 2520
multiply both-side of the equation by 2520
48×2520 = 269.5Ф
120960 = 269.5Ф
divide both-side of the equation by 269.5
448.8≈Ф
Ф = 448.8°
The angle it turns through if it  sweeps an area of 48 cm²   is   448.8°
