Answer:
Explanations:
To convert angles from degrees to radians, multiply the angle by π/180
For angle 126°, the equivalent measurement in radian is:

Reduce to the lowest term by dividing the numerator and denominator by 18:
Answer:
-4320t^2
Step-by-step explanation:
Use Pascal's triangle to figure out the variables.
In the 5th expansion, we see that the 4th term is:
10x^2 y^3
Plug in the values,
10*(4)^2 * (-3)^3 = -4230.
However, since the -3 in the original expression does not have a variable next to it, we do not include it in our answer.
Therefore, the 4th term is -4230t^2
The answer is attached. I hope this helps answer your question!
