Answer:

Angle #1 is 45 degrees

Angle #2 is 60 degrees

Angle #3 is 75 degrees

Step-by-step explanation:

x- angle #1

y- angle #2

(180-x-y)- angle #3

3x=180-x

4x=180

x=45

180-x-y=y+15

y=60

180-60-45=

180-105= 75

It has 4 vertices and edges

Si p+ 2p+3p=12, ¿cual es el valor de 5p -1
Nutka1998 [239]

For this case we have the following equation:

p + 2p + 3p = 12

To solve we follow the steps below:

We add similar terms from the left side of the equation:

6p = 12

We divide between 6 on both sides of the equation:

p = \frac {12} {6}\\p = 2

Finally, we have to:

5p-1 = 5 (2) -1 = 10-1 = 9

Answer:

p = 2\\5p-1 = 9

The sum of three consecutive even numbers is one hundred sixty - two.
Alenkasestr [34]

Answer:

 52

Step-by-step explanation:

Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...

  x + (x+2) +(x+4) = 162

  3x = 156 . . . . . . . . . . . .subtract 6

  x = 156/3 = 52

The smallest of the three numbers is 52.

___

I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.
