Slav-nsk [51]

\frac{x}{18}  and  \frac{3}{18} both have a common denominator, so you can combine them into a single fraction:

\frac{x}{18}+\frac{3}{18}=\frac{x+3}{18}

You cannot simplify this fraction further:

- - - - - - - - - - - - - - - - - - - -

Answer:

\boxed{\frac{x+3}{18}}

Need help asap pls :)
pogonyaev

Answer:

See explanation below.

Step-by-step explanation:

First I'm going to find angle 2. Angle two plus 55 is equal to 115. 180-115=65. 65-55=10 Angle 2 = 10

Next, we can find angle 3. 55+10=65. 180-65=115. Angle 3 = 115

Angle 2 is equal to angle 5, angle 3 is equal to angle 6, and angle 4 is equal to 55.

Angle 5 = 10

Angle 4 = 55

Angle 6 = 115

Now we can find angle 8. 180-115=65. Angle 8 = 65

Angle 11 = 65

Angle 12 = 115

10+115=125 Angle 10 = 125

180-125 = 55 Angle 9 = 55

Angle 14 = 55

Angle 13 = 125
