Answer:
<u>TO FIND :-</u>
- Length of all missing sides.
<u>FORMULAES TO KNOW BEFORE SOLVING :-</u>
<u>SOLUTION :-</u>
1) θ = 16°
Length of side opposite to θ = 7
Hypotenuse = x


 ≈ 25.3
 ≈ 25.3 
2) θ = 29°
Length of side opposite to θ = 6
Hypotenuse = x


 ≈ 12.3
 ≈ 12.3 
3) θ = 30°
Length of side opposite to θ = x
Hypotenuse = 11


 
 
4) θ = 43°
Length of side adjacent to θ = x
Hypotenuse = 12


 ≈ 8.8
 ≈ 8.8 
5) θ = 55°
Length of side adjacent to θ = x
Hypotenuse = 6


 ≈ 3.4
 ≈ 3.4
6) θ = 73°
Length of side adjacent to θ = 8
Hypotenuse = x


 ≈ 27.3
 ≈ 27.3
7) θ = 69°
Length of side opposite to θ = 12
Length of side adjacent to θ = x


 ≈ 4.6
 ≈ 4.6 
8) θ = 20°
Length of side opposite to θ = 11
Length of side adjacent to θ = x


 ≈ 30.2
 ≈ 30.2 
 
        
             
        
        
        
You can either use a caculator or use pencil and paper if you know how to times the numbers line them up then time it ill show you
 
 
        
        
        
Answer:
The answer is 1 side must measure 90
Step-by-step explanation:
 
        
                    
             
        
        
        
Using cosine law and considering the angle ABC is 89 you can deduce that AC is 6.3 
6<6.3 
So the largest possible integer is 6
        
             
        
        
        
We make the composition of both functions:
 f (x) = x ^ 2-1
 g (x) = 2x-3
 Then:
 f (g (x)) = (2x-3) ^ 2-1
 Rewriting:
 f (g (x)) = 4x ^ 2-12x + 8
 The domain of this function is all real numbers.
 Equivalently
 x: (-inf, inf)
 answer:
 x: (-inf, inf)
