CAN SOMEONE HELP ME WITH WIYH THIS ?????

Answer:

x = 14

Angle B = 121°

Angle C is 59°

Step-by-step explanation:

First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)

10x-19 = 7x+23 subtract 7x

3x-19 = 23 add 19

3x = 42 divide by 3

x = 14

Angle B is 10x-19, and if x=14, then its 10(14)-19

Angle B is 140-19

which is 121°

Angle B = 121°

Angle B and Angle C add up to 180°

121° + c = 180°

c = 180-121

Angle C is 59°

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,

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