Answer:

[tex]\huge\boxed{\sf x = 3 }[/tex]

Step-by-step explanation:

If the measure of :

∠CBD = 5 ( 7x + 15 )

Also,

∠CBD = 180°

Then,

5 (7x + 15) = 180

35x + 75 = 180

Subtract 75 to both sides

35x = 180 - 75

35x = 105

Divide both sides by 35

x = 105 / 35

x = 3

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!
