Step-by-step explanation:

The binomial theorem states that for some a,b∈R and some k ∈Z+ ,
(a+b)k=∑n=0k(kn)ak−nbn.
The binomial series allows us to use the binomial theorem for instances when k is not a positive integer. The binomial series applies to a given function f(x)=(1+x)k for any k∈R with the condition that |x|<1 . It is stated as follows:
(1+x)k=∑n=0∞(kn)xn .
Note that the binomial theorem produces a finite sum and the binomial series produces an infinite sum.
Answer:
∠TUV = 120°
Step-by-step explanation:
Since this figure is a kite, we know that; ∠TUV ≈ ∠TWV, so first we solve for x:
9x - 6 = 7x + 22
2x - 6 = 22
2x = 28
x = 14
Now, substitute 14 in for x, in the equation for ∠TUV:
∠TUV = 9x - 6
∠TUV = 9(14) - 6
∠TUV = 126 - 6
∠TUV = 120°
Hope this helps!
First you have to find the angle B (check attachment)

Then you can find the last angle inside the triangle, which I'll call C

Now you can find angle A
