Answer:

3√3 = l

√3 = w

Step-by-step explanation:

l = 3w

9 = 3w[w] ↷

9 = 3w² [Divide by 3]

3 = w² [Take the square root]

√3 = w [plug this back into the top equation to get a length of 3√3]

[3√3][√3] = 9 [Area]

If W is the center of the circle below and measures 52°, what is the measure of XZY?
Zinaida [17]

Answer:

Option (B)

Step-by-step explanation:

By the theorem of the inscribed angle,

"An angle inscribed in a circle measures half of the central angle subtended by the same arc."

Since m(arc XY) = 52°

Angle subtended by the the arc at the center (Central angle) = m∠XWY = 52°

Measure of inscribed angle = m∠XZY

By theorem, m∠XZY = \frac{1}{2}(\angle XWY)

m∠XZY = \frac{1}{2}(52)

             = 26°

Therefore, Option (B) will be the answer.
