Answer:
65º
Step-by-step explanation:
- The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
- The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
- We can solve from there, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 230, -2x=-50
- Divide by -2, x=25
- m∠CAB=(x+40)º=(25+40)º=65º
- m∠ABC=(180-6x)º=(180-150)º=30º
- m∠BCA=(3x+10)º=(75+10)º=85º

It is a ray, you can tell because it goes on only on one side while a line segment would have two solid dots/finite points on both ends. :))
Answer:
There are 32 marbles. 11 are red. So odds of a red on the first are 11/32.
Now there are 31 marbles left. 10 are red. So odds of a red on the second is 10/31.
Probability both are red, just multiply …. 11/32x 10/31 = 110/992 or 0.111.
