The sum of the opposite interior angles is equal to the exterior angle.
So,
∠CAB + ∠ACB = ∠CBD
x + 40 + 3x + 10 = 6x
4x + 50 = 6x
2x = 50
x = 25°
∠CAB = x + 40 = 25 + 40 = 65°
Hence, the answer is D.
The property displayed here is the distributive property.
If you have a variable or unknown number inside or outside of parentheses, you can distribute it to each term and add the terms together, and it will remain true.
Example:
4(x + 5)
After distributing, it'll look like this:
4x + 20

Yes it is!!!!!!!!!!!!!!!!!!!!!
Answer:
k = 2
Step-by-step explanation:
5k = 6k + 4 - 6
We can simplify this by solving 4 - 6 (replacing it with -2 !)
5k = 6k - 2
Now we can subtract 5k from both sides.
0 = k - 2
Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.
2 = k
Just reversing it...
k = 2
Answer: k = 2
