Answer: 78°

Step-by-step explanation:

Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.

4x+2+3x+3=180 [combine like terms]

7x+5=180 [subtract both sides by 5]

7x=175 [divide both sides by 7]

x=25

Now that we know x=25, we can plug it in to find ∠DCB.

3(25)+3 [multiply]

75+3 [add]

Now, we know ∠DCB is 78°.
