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
Answer:
x =64.5
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
The total circle is 360 degrees
The arc is 360 - 113 - 118
arc =129
x = 1/2 (129)
x =64.5
Plug in 0 for y and then solve for x, then plug in 0 for x in the starting equation to solve for y, the resulting two values are your x and y ordered pair.
12x+6y=24
12/6 24/6
2 4
2x=4
4/2=2
Therefore x=2
