Answer:

x=12

Step-by-step explanation:

142 and 3x+2 are supplementary angles when the lines are parallel

142+ 3x+2 = 180

Combine like terms

144+3x= 180

Subtract 144 from each side

144+3x-144=180-144

3x=36

Divide by 3

3x/3 = 36/3

x =12

Answer:

The distributive property helps in making difficult problems simpler. You can use the distributive property of multiplication to rewrite expression by distributing or breaking down a factor as a sum or difference of two numbers.

Here, for instance, calculating 8 × 27 can made easier by breaking down 27 as 20 + 7 or 30 − 3.
