78 Degrees

Step-by-step explanation:

Two supplementary angles:

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

Angle DCB is 78 degrees

78 Degrees

Step-by-step explanation:

Two supplementary angles:  (GIven)

4x + 2 + 3x + 3 = 180

Combine like terms:

7x + 5 = 180

Simplify

7x = 175

x = 25

(25)3 + 3 = 75 + 3 = 78

So,

Angle DCB is 78 degrees.

I hope it will help you :)

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
