Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2
approximately
Answer:
44° and 46°
Step-by-step explanation:
Complementary angles sum to 90° , thus
x + x + 2 = 90
2x + 2 = 90 ( subtract 2 from both sides )
2x = 88 ( divide both sides by 2 )
x = 44
Thus the 2 angles are 44° and 44 + 2 = 46°
