Answer 1

Respuesta:

13) B = 91/12

14) D = 481/255

15) F = 32/5

16) K = 247/35

Explicación paso a paso:

13) tan∝ = 18/24 = 3/4

cot∝ = 24/18 = 4/3

B = 3tan∝ + 4cot∝

B = 3(3/4) + 4(4/3)

B = 9/4 + 16/3

B = $\frac{27+64}{12}$

B = 91/12

14) $h^{2}=30^{2}+16^{2}$

$h^{2}$ = 900 +256

$h^{2}$ = 1156

h = $\sqrt{1156}$

h = 34

sen∝ = 16/34 = 8/17

cos∝ = 30/34 = 15/17

tan∝ = 16/30 = 8/15

D = sen∝ + cos∝ + tan∝

D = 8/17 + 15/17 + 8/15

D = 23/17 + 8/15

D = $\frac{345+136}{255}$

D = 481/255

15) sen∝ = 28/35 = 4/5

cos∝ = 21/35 = 3/5

tanβ = 21/28 = 3/4

F = 2sen∝ + 3cos∝ + 4tanβ

F = 2(4/5) + 3(3/5) + 4(3/4)

F = 8/5 + 9/5 + 3

F = 17/5 + 3

F = 32/5

16) tanФ = 35/12

secβ = 37/35

K = tanФ + secβ + tanФ.secβ

K = 35/12 + 37/35 + 35/12 . 37/35

K = 35/12 + 37/35 + 37/12

K = $\frac{1225+444+1295}{420}$

K = 2964/420 = 247/35
