Complete the following proof.Given: m ∠XOY = m ∠WOV
m YZ = m ZW
Prove: m XZ = m ZV

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

{ If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW ------- (ii) {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV

Hence proved.

Answer 2

Answer:

Answer:

Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.

Given: m YZ = m ZW

The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ

The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV

Then, m XZ = m ZV

D)

Answers

A) 6 x 3 = 18

B) 6 x 6 x 6 = 6^3 = 216

C) 3 x 3 x 3 x 3 x 3 x 3 = 3^6 = 729

D) (3 x 2) x (3 x 2) x (3 x 2) = 6 x 6 x 6 = 216

None of these equal to 63.

There are no correct answers because

A=18
B=216
C=729
D=216

So no answers are correct because none equal 63.

Susan, Lillian, John, and Polly participated in an Easter egg hunt. At the end of the hunt, 96 eggs were shared equally among them. How many Easter eggs did each of the receive?

Answers

My way of solving this problem is making variables. 4 = people because there was 4 people then you do 96 / people = 24

Nicole bought a meal in a town that has no sales tax. She tips 20%. Select all meals Nicole could buy for less that $15 total.

Answers

I'm missing some information... but I'll answer the question regardless

x=the cost of the meal

1.2x≤$15
divide both sides by 1.2
x≤$12.5

In short, this means that Nicole can buy anything that costs $12.50 or less.
