HELP WITH ANGLE THEOREMS! Brainliest! Find the values of c and d.

Mathematics

tatuchka [14]4 years ago

Answer:

c = 25, d = 65

Step-by-step explanation:

∠d + 90 = 155 ( vertical angles )

Subtract 90 from both sides

d = 65

The angle above 155 = 180 - 155 ( straight angle ) = 25

Hence c = 25 ( corresponding angles )

Answer:

<d = 65 degrees.

<c = 25 degrees.

Step-by-step explanation:

<d + 90 = 155 since vertically opposite <'s are equal. Therefore <d = 155-90

= 65 degrees.

The angle adjacent to <d is 180-155= 25 degrees since <'s on a line = 180 degrees.

Therefore <c= 25 degrees since corresponding <'s on parallel lines are equal.

el precio del kilogramo de jitomate es de 36.50 juana compro 3 1/2 kilogramos cuanto pago por todo el jitomate?​
SashulF [63]

El precio total por 3 1/2 kg de jitomate que compró Juana es 127.75

Para saber el precio total de los 3 1/2 kg de jitomate que compró Juana debemos hacer el siguiente procedimiento.

Necesitamos saber cuánto vale medio kg de jitomate, para ello dividimos 36.50 en 2.

36.50/2 = 18.25

Luego multiplicamos 36.50 por 3, para saber cuánto valen 3 kg de jitomate.

36.50 X 3 = 109.5

Por último, sumamos el precio de medio kilo con el precio de tres kilos para tener el total que pagó Juana.

109.5 + 18.25 = 127,75

Find a formula for the sum of the first n even positive integers.
melisa1 [442]
So even postive integers are by defention in form 2k where k is a natural number so
let the sum of even integers to n=S
S=2(1+2+3+4+5+6+7+8+......+k-1+k
divide bith sides of equation 1 by 2
0.5S=1+2+3+4+5+...........+k-1+k
S=2(k+(k-1)+..............................+2+1)
divide both sides of equation 2 by 2
0.5S=k+k-1+..............................+2+1)
by adding both we will get
___________________________
S=(k+1)(k)
so the sum will be equal to
S=
{k}^{2}  + k
so let us test the equation
for the first 3 even number there sums will be
2+4+6=12
by our equation 3^2+3=12
gave us the same answer so our equation is correct
