What is the measure of angle 42
O 30°
O 420
O 120°
O 1389

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
