Ithink the third statement (z=t) is right but i'm not i. x=z ii. y=w iii. z=t a) i and ii only b) i and iii only c) ii and iii only d) i, ii, and iii

I and III seem to be correct, II doesn't because, for example, if x = w = z = t = 70 and y = u = 40, then all three pairs of vertical angles in the figure have equal measure and the given condition x + y = u + w stands. But it means y is not equal to w.

Your answer should be B)

8%

Step-by-step explanation:

I=Pr

104=2600*r/2

r/2=104/2600

r=(104/2600)(2)

r=0.08=8%
