Answer:

x=15

Step-by-step explanation:

I gotcha bro

The line C is straight and straight lines are 180°

so 180° = 4x + 8x = 12x ----> 180 = 12x ---> then divide both sides by 12

180/12 = 15   and 12x/12 = x

so 15 = x or x = 15

Answer:

x = 15

Step-by-step explanation:

We know that 4x° + 8x° make a straight angle of 180°.

4x° + 8x° = 180°

12x° = 180°

12x = 180

x = 180/12 = 15

Debora [2.8K]

Answer:

Step-by-step explanation:

4 (x+7) = 6x+20

The +20 is necessary because the left is twenty less, so in order to make them equal we must add twenty to the right.

Continue and solve by isolating integrates on one side and numbers on the other.

X=4
