Answer:
BC = 2
Step-by-step explanation:
We first need to use triangle BAD to find BD,
BD is the hypotenuse, so use pythagorean theorem...
(√23)² + (√13)² = (BD)²
23 + 13 = (BD)²
36 = (BD)²
6 = BD
Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC
(4√2)² + (BC)² = 6²
32 + (BC)² = 36
(BC)² = 4
BC = 2

Answer:
area of shaded region: 21.07 ft²
<u>Given for semi circle:</u>
- radius of semi-circle: 7 ft
<u>Given for rectangle:</u>
<u>Find area of rectangle:</u>
Length * Width
14 * 7
98 ft²
<u>Find the area of semi circle:</u>
1/2 * π * r²
1/2 * 3.14 * (7)²
76.93 ft²
<u>Area of shaded region:</u>
area of rectangle - area of semi-circle
98 ft² - 76.93 ft²
21.07 ft²

Answer:
a = 36.37 cm
c = 18.19 cm
Step-by-step explanation:
to find a, use tan
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 1.732
⇒ 1.732 =
multiply 21 on both sides
⇒ 1.732 x 21 = x 21
⇒ 36.37 = a
to find c, use sine
⇒ sine = 
⇒ sine 60 = 
sine of 60 is 0.866
⇒ 0.866 =
muliply 21 on both sides
⇒ 0.866 x 21 = x 21
⇒ 18.19 = c
