Does anyone know how to do #11 ? i need your again : (

Step-by-step explanation:

Four consecutive counting numbers would look like this

x

x + 1

x + 2

x + 3

Do you see that these numbers are 1 larger than the one before it. So if x is 20 the numbers would be 20 21 22 23

Now take the 4 general numbers and add them

x + x + 1 + x+2 + x + 3

4x + 6

Two will go into 4x to give 4x/2 = 2x

Two will go into 6 to give 6/2 = 3

Always happens. There are no exceptions. Try x = 20 again

20 + 21 + 22 + 23 = 86

Can this number be divided by 2? Yes it can 86/2 = 43

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
