If the measure of angle CBD is 5(7x + 15) degrees, then what is the value of x. (Angle CDB is 180) x =

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

Hope this helped!

the answer is c

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
