Answer:
   perimeter ≈ 12.4 units
Step-by-step explanation:
The side adjacent to the angle is given. The relationships useful for the other two sides are ...
   Tan = Opposite/Adjacent
   Cos = Adjacent/Hypotenuse
From these, we have ...
   opposite = 5·tan(22°) ≈ 2.02
   hypotenuse = 5/cos(22°) ≈ 5.39
Then the perimeter is ...
   P = a + b + c = 2.02 + 5 + 5.39 = 12.41
The perimeter of ∆ABC is about 12.4 units.
 
        
             
        
        
        
Answer:
0
Step-by-step explanation:
Angle x+45  = (145-55) / 2
2x + 90 = 90
2x = 0
x = 0
 
        
             
        
        
        
You draw a number line do +100 on the line then do +100 +100 +50 +8 then you add them up
        
             
        
        
        
Answer:
The area of the shaded region is 17.4 square meters.
Step-by-step explanation:
Since the shaded region in the center equals the remainders of a circle, the area of a square equals its side squared, and the area of a circle equals π times the radius squared, for To determine the area of the shaded region, the following calculations should be performed:
(9 ^ 2) - (π x (9/2) ^ 2) = X
81 - (π x 4.5 ^ 2) = X
81 - (3.141 x 4.5 ^ 2) = X
81 - 3.141 x 20.25 = X
81 - 63.6 = X
17.4 = X
Thus, the area of the shaded region is 17.4 square meters.
