Answer:

The angles are 160 and 20 degrees respectively

Step-by-step explanation:

angles on a line sum to 180 degrees.

This tells us that (5x + 60) + (3x -40) = 180

we can expand brackets to give 8x + 20 = 180

8x = 160

x = 20 degrees

In the expansion of
Mumz [18]

By the binomial theorem, the x^2 term in the expansion of \left(1-\frac x4\right)^n is

\dbinom n21^{n-2}\left(-\dfracx4\right)^2=\dfrac{n!}{2!(n-2)!}\dfrac{x^2}{16}

which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,

\dfrac{n!}{2!(n-2)!}=\dfrac{n(n-1)}2=21\implies n=7
