angle1 = x

angle2 = x - 58

given,

these are supplementary angles

Therefore,

(x) + (x - 58) = 180

x + x - 58 = 180

2x - 58 = 180

2x = 180 + 58

2x = 238

x = 238/2

x = 119

<u>angle1 = 119</u>

<u>angle1 = 119angle2 = 61</u>

Answer:

i think it is 122 degrees, as the solution would be to subtract 58 from 180

Step-by-step explanation:

180-58=122

For every 9 black and white copies printed there are 2 color copies printed. If there are 200 color copies printed how many blac
alexandr402 [8]

Answer:

<u>900</u> black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be x.

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, x is equivalent to 200.

Now, to solve by using cross multiplication method:

\frac{9}{2} =\frac{x}{200}

<em>By cross multiplying we get:</em>

1800=2x

<em>Dividing both sides by 2 we get:</em>

900=x

x=900.

Therefore, 900 black and white copies are printed.

si franco comió 8/3 de pizza y Fabián comió 5/6 de la misma pizza. ¿quien comió más ? si quedó 4/9 de pizza.​
devlian [24]

Answer:

Franco comió 8/3 de pizza.

Fabián comió 5/6 de pizza.

Queremos saber quien comió más.

Entonces básicamente queremos ver cuál número es más grande, 8/3 o 5/6,

Podemos reescribir el primero como:

8/3 = (2 + 3 + 3)/3 = 2/3 + 3/3 + 3/3 = 2/3 + 1 + 1

      = 2 + 2/3

En cambio, para el número 5/6, el numerador es menor que el denominador, entonces sabemos que:

5/6  < 1

Claramente podemos ver que 8/3 > 5/6

Entonces podemos concluir que Franco comió más.

Eight angles of a nonagon measure 1389, 154º. 145°, 132°, 148°, 143,
PIT_PIT [208]

Answer:

103°

Step-by-step explanation:

The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.

138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157

1260 - 1157 = 103

Therefore, the missing angle is 103°
