PQ is the tangent, therefore you can use a theorem: The arc measure is double the amount of the angle the tangent makes.
So: 62/2=31
Answer:
4
Step-by-step explanation:
2x+19=x+23
We simplify the equation to the form, which is simple to understand
2x+19=x+23
We move all terms containing x to the left and all other terms to the right.
+2x-1x=+23-19
We simplify the left and right sides of the equation.
+1x=+4
We divide both sides of the equation by 1 to get x.
x=4

Explanation:
Since {v1,...,vp} is linearly dependent, there exist scalars a1,...,ap, with not all of them being 0 such that a1v1+a2v2+...+apvp = 0. Using the linearity of T we have that
a1*T(v1)+a2*T(v1) + ... + ap*T(vp) = T(a1v19+T(a2v2)+...+T(avp) = T(a1v1+a2v2+...+apvp) = T(0) = 0.
Since at least one ai is different from 0, we obtain a non trivial linear combination that eliminates T(v1) , ..., T(vp). That proves that {T(v1) , ..., T(vp)} is a linearly dependent set of W.
