Plz help. Draw line ZY parallel to segment PQ Construction m∠ZRP + m∠PRQ + m∠QRY = m∠ZRY Angle Addition Postulate

∠ZRP ≅ ∠RPQ Alternate Interior Angles Theorem

∠QRY ≅ ∠PQR Alternate Interior Angles Theorem

m∠RPQ + m∠PRQ + m∠PQR = m∠ZRY Substitution

m∠ZRY = 180° Definition of a Straight Angle

m∠RPQ + m∠PRQ + m∠PQR = 180° Additive Property of Equality

Which statement will accurately correct the two-column proof?

A. The measure of angle ZRY equals 180° by definition of supplementary angles.

B. Angles QRY and PQR should be proven congruent before the construction of line ZY.

C. The three angles of ΔPQR equal 180° according to Substitution.

D. Line ZY should be drawn parallel to segment QR.

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

You and three friends will be going out to eat at your favorite restaurant! each of you will order three items of your choice. you will also need to leave a tip. if you split the bill evenly among all four of you, how much will each person need to contribute? locate a menu for your favorite restaurant and pick three items for yourself and each friend. list the restaurant name, items, and prices in a table like the one below. in the column labeled subtotal, determine the cost of each person’s order. the customary tip is 20% of the total bill. in the column labeled tip, calculate the amount of tip each person should leave. in the column labeled total bill, determine the total of each person’s order, including the tip. restaurant name: names item 1 price item 2 price item 3 price subtotal tip total bill your name friend #1 friend #2 friend #3 part 2: questions answer the following questions, showing all work: what is the total cost of the entire bill (all four meals), including tip? write an expression using fractions to show how to determine the amount that each person will pay. then calculate each person's contributions showing all steps in long division. if each person paid an equal amount, who would save the most money? explain your reasoning using at least two complete sentences.
