Answer:

42°

Step-by-step explanation:

angle 3 + angle 4 = 180° because together they make a straight line. So your equation should be 23x + 7x = 180. Add the like terms and you get 30x=180. Divide by 30 on both sides to get x. now you know that x=6. angle 4 = 7x. so you would multiply 7*6 to get 42. Thus angle 4= 42°

Answer:

42 degrees

Step-by-step explanation:

<3 and <4 form a straight line so their sum is 180 degrees

<3 + <4 = 180

23x + 7x = 180

Combine like terms

30x = 180

Divide each side by 30

30x/30 =180/30

x =6

We want to find <4

<4 = 7x

    = 7*6

<4 = 42 degrees
