This is because the probability of pulling a red is 1/3. Multiply that by itself to find the chance of repeating.
Subst for f and t in...
9t+3ft+12 = 9×21 + 3×3×21 + 12 = 390
Answer:
C. Four right angles are created
Step-by-step explanation:
This is because right angles are formed usually by polygons so in this case it wouldn't be any different.
- At the cause of it being polygons, it also helps it to be parallel lines, which it is.
Leading it to be further more right angles.
Now how do we get four right angles?
We get four right angles by seeing the right inscribed "measurements", by at least seeing it in the "usual" contact.
I hope this helps, If I did something wrong please tell me!
Have a good day!
Every point in the unit circle is identified either by its coordinates 
or by the angle it forms with the x-axis, 
.
The trigonometric functions associate with every angle and the correspondant coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.
