Answer:
Option C: 41
Step-by-step explanation:
<ABD+<CBD=90
<ABD=8x+1
<CBD=6x+5
(8x+1)+(6x+5)=90
Combine like terms
(8x+6x)+(1+5)=90
14x+6=90
14x=90-6
14x=84
divide both sides by 14
x=6
Now we plug that value into <DBC = 6x+5
6(6)+5=
36+5
41
Point D is (4,4)
and the idea is just simply substituting with D into (6x+5y) as follows:
6x+5y = 6*4 + 5*4 = 24 + 20 = 44
That is it
