If BC bisects angle ABD, and angle abc=5x+11 angle CBD=10x-4
a.5
b.3
c.1
d.2
well, you have
5x+11 = 10x-4
other than that, no clue what the question is. I think it's "what is x?"
@steve it is asking what is x
and can you not solve the equation I gave? I assume you have had Algebra I.
-5x+11=-4
-5x=-15
x=3
its 3
To find the value of x in this geometry problem, we can use the fact that angle ABC and angle CBD form a straight line when added together. Since BC bisects angle ABD, angle ABC and angle CBD are equal.
Therefore, we can set up an equation:
angle ABC + angle CBD = 180 degrees.
Substituting the given values, we have:
(5x + 11) + (10x - 4) = 180
Combining like terms:
15x + 7 = 180
To isolate x, we need to subtract 7 from both sides:
15x = 180 - 7
15x = 173
Finally, we divide both sides by 15 to solve for x:
x = 173 / 15
Calculating the value of x:
x = 11.53
Since none of the answer choices are equal to 11.53, it seems there may be an error in the given problem or answer choices.
