When two lines intersect, four angles are formed. According to Euclid's fourth postulate, which pair of intersecting lines would form
four congruent angles?
y = 8x + 1 and y = -8x - 3
y = 2x + 5 and y = kx + 4
y=-3x - 6 and y = 7* - 9
ya Ex - 1 and y = 4x + 2

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

The reflexive property of congruence lets you say that ∠pqr ≅
