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 
 
        
             
        
        
        
Answer: C
Step-by-step explanation:
A= 1/2(a+b)xh
A=1/2(7+10)x5
A=8.5x5
A=42.5
