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!

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
