the measure of (arc)xy is 94*. what is the measure of xyz, the tangent-chord angle?
can u also tell me how to answer?

Option A. 47°

Step-by-step explanation:

Since m(Arc)XY = 94°

Therefore angle at the center = 94°

Now in triangle formed at the center  

∠XOY = 94°

Now ∠OXY+∠XYO = 180 - ∠YOX = 180 - 94 = 86

and we know ∠OXY = ∠XYO

therefore ∠XYO = 86/2 = 43°

Now ∠XYO + ∠XYZ = 90°

∠XYZ = 90 - ∠XYO = 90 - 43 = 47°

Option A 47° is the answer.

22 dimes and 9 nickels

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
