Answer 1

Odpowiedź:

a)

h/5 = 1/2    /*5

h = 2,5 j

5^2 = 2,5^2 + x ^2

25 = 25/5 + x^2

x^2 = 18,75

x = 2,5 j

2,5/b =   /*b

b = 2,5   /

b = 5/√2 = 2,5√2 j

(5/√2)^2 = 2,5^2 + y ^2

25/2 = 25/4 + y^2

y^2 = 25/4

y = 5/2 j

Obwód = 2,5√3 + 2,5√2 + 5 + 2,5 = 7,5 + 2,5√3 + 2,5√2 j

Pole = (2,5 + 2,5)  * 2,5 * 0,5 = (25 + 25√3)/8 j^2

b)

h/4 =  √3/2      /*4

h = 2√3 j

6^2 = (2√3)^2 + x^2

36 = 12 + x^2

X^2 = 24

x = 2√6 j

2√3/c = 1/2      /*c

1/2c =  2√3

c = 4√3 j

(4√3)^2 = (2√3)^2 + y ^2

48 = 12 + y^2

y^2 = 36

y = 6 j

P = 0.5 * (6+2√6)  * 2√3 = (3+√6) * 2√3  = 6√3 + 6√2 j^2

Obwód = 6 + 4√3  +6 + 2√6 = 12 + 4√3  + 2√6 j

c)

√3/c =  1/2     /*c

√3 = 1/2c

c = 2√3  j

(2√3 )^2 = √3^2 + a^2

12 = 3 + a^2

a^2 = 9

a = 3 j

Obwód = 9 + 2√3 + √3 = 9 + 3√3 j

P = √3 * 0.5 * 3 = 1,5√3 j^2

d)

h/4 = √3/2    /*h

h = 2√3

4^2 = (2√3)^2 + x^2

16 = 12 + x^2

X^2 = 4

x = 2 j

2√3/c = √2/2   /*c

√2/2c = 2√3     /√2/2

c = 2√6 j

(2√6)^2 = (2√3)^2 + y^2

24 = 12 + y^2

y^2 = 12

y = 2√3 j

Obwód = 2√6 + 2 + 2√3 + 4 = 6 + 2√6 + 2√3 j

Pole = 0.5 * 2√3 * (2+2√3) = 6 + 2√3 j^2

e)

5√3/h = 3/√3           /*h

5√3  = 3/√3 h   / 3/√3

h = 5  j

c^2 = 5^2 + (5√3)^2

c^2 = 25 + 75

c^2 = 100

c = 10 j

5/b = √2/2   /*b

√2/2b  = 5    /√2/2

b = 10/√2 = 5√2 j

(5√2)^2 = 25 + y^2

y^2 = 50 - 25 = 25    /√

y = 5 j

Obwód = 10 + 5√2 + 5 + 5√3 = 15 + 5√2 + 5√3 cm

Pole = 0.5 * 5 * (5√3 + 5) = 12,5 + 12,5√3  cm^2

f)

h/4√2  = √2/2        /*4√2

h = 4 j

4/c = 1/2    /*c

1/2c  = 4    /*2

c = 8 j

(4√2)2 = 4^2  + x^2

32 = 16+ x^2

x^2 = 16

x = 4 j

8^2 = 4^2 + y^2

64 = 16 + y62

y^2 = 64 - 16 = 48       /√

y = 4√3 j

Obwód = 4√2 + 8 + 4 + 4√3  = 12 + 4√2 + 4√3 j

Pole = 0.5 * 4 * (4+4√3) = 8 + 8√3  j^2
