Answer:

x = 14

Step-by-step explanation:

The angles form a straight line which makes them add to 180 degrees

4x+ 8x+12 =180

Combine like terms

12x+12 =180

Subtract 12 from each side

12x+12-12 = 180-12

12x=168

Divide each side by 12

12x/12 =168/12

x =14

¿Cuáles son el término 100 y el término 273 de la sucesión?<br> 2, 4, 6, 8, 10, 12

inn [45]

Answer:

200 and 546

Step-by-step explanation:

dejar a = Primer periodo (first term)

dejar d = Diferencia común (common difference)

dejar 100th término = T100

dejar 273 término = T 273

utilizando

Tn = a + (n - 1)d

T100 = 2 + (100 - 1) 2

= 2 + 99 ×2

= 2 + 198

= 200

T273 = 2 + (273 - 1) 2

= 2 + 272 × 2

= 2 + 544

= 546

Determine two coterminal angles in degree measure (one positive and one negative) for each angle. (There are many correct answer

Nat2105 [25]

Answer:

(a) Coterminal =495, -225

(b) Coterminal = 135,-585

Step-by-step explanation:

The angles are:

(a) 135° (b) −225°

The coterminal angle of angle x is derived by:

$Coterminal = x \± 360$

Solving (a): 135°

Substitute 135 for x in $Coterminal = x \± 360$

$Coterminal =135 \± 360$

Split

$Coterminal =135 + 360, 135 - 360$

$Coterminal =495, -225$

Solving (b): -225°

Substitute -225 for x in $Coterminal = x \± 360$

$Coterminal =-225 \± 360$

Split

$Coterminal = -225 + 360,-225 - 360$

$Coterminal = 135,-585$
