Answer:
The length of each side is 26.3 cm
Step-by-step explanation:
Opposite sides of an isoceles triangle are equal
The isoceles triangle is divided into 2 right-angled triangles so the length of one side can be calculated using trigonometric ratio
When the isoceles triangle is divided, the angle in the right-angled triangle is 20° (1/2 of 40°) and the base is 9cm (1/2 of 18 cm), the hypotenuse side is calculated using trigonometric ratio
Let the length of the hypotenuse side be y
9/y = sin 20°
y = 9/0.3420 = 26.3
Length of each side is 26.3 cm
 
        
             
        
        
        
Answer:
<h2>          

</h2>
Step-by-step explanation:
25 - 32 = -7  and 18 - 25 = -7
It means an arithmetic sequence with common difference d = -7

 
        
             
        
        
        
State C spent $28.3 million and State D spent $26.3 million.
Step-by-step explanation:
Total spent for tourism = $54.6 million
Let, 
The amount spent by State C = x
The amount spent by State D = y
According to given statement; 
x+y = 54.6    Eqn 1
x=y+2    Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting y=26.3 in Eqn 2

State C spent $28.3 million and State D spent $26.3 million.
