Can someone help me please? Lines AB and CD are perpendicular to each other. If 1 measures (3x + 3)°, and 2 measures 39°, what is the value of x?

x=16

angle 3=51

angle 4=39

Step-by-step explanation:

1) since angles 1,2 and 3,4 are vertical from each other we can use vertical angle therom (vertical angles are equal to each other)

angle 1 and 2 make a 90 degree angle

so

3x+3+39=90

3x+42=90

3x=48

x=16

lets plug in "16" as "x"

3(16)+3=51

IF you wanted to find out what angle 3 and 4 is

angle 3=51(opposite  of angle 1)

angle 4= 39 opposite of angle 2

x=4
