Question

ayudenme con estas 4 porfavor doy corona al que me ayude​

Answer 1

Explicación paso a paso:

1)

140^g = abc°

Entonces, recuerda: 10^g = 9°

140^g(9°/10^g) = 126°

Dónde: 126° = abc° (a=1, b=2,c=6)

$\sqrt{1 + 2 + 6} = \sqrt{9} = 3$

2)

Recuerda: 2π = 360° por tanto: π = 180°

3π/20 = 3(180°)/20 = 27°

Entonces:

4x + 10 = 27

4x = 17

x = 17/4 = 4.25 (No hay Clave)

3)

(180-@) - (180-&) = π/3 = 180/3 = 60°

& - @ = 60° (&>@)

& + @ = 180

sumando:

2& = 240

& = 120°

4)

Volvemos todos los ángulos a un mismo sistema:

50^g = 50^g(9°/10^g) = 45°

π/3 = 180°/3 = 60°

40^g = 40^g(9°/10^g) = 36°

π/6 = 180/6 = 30°

Entonces:

$\frac{25 + 45 + 60}{64 + 36 + 30} = \frac{130}{130} = 1$

5)

π/64 = 180/64 = 2.8125° = 2° + 0.8125° = 2° + 48.75'

= 2° + 48' + 0.75' = 2°48' + 45'' = 2°48'45''

Por tanto: x = 2 , y = 48 , z = 45

x + y - z = 2 + 48 - 45 = 5°

El complemento será: 90 - 5 = 85°
