Q1. A square is divided by its diagonals into four triangles. Answer question(a) and question(b) below. a. What do you notice about the following angle pairs?
aº and bº
cº and dº
cº and eº

b. Find the values of the indicated variables.
Do not use a protractor to measure the angles.
с =
d =
e =
Explain how you obtained each answer.​

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.

step-by-step explanation:

=

x=0.8898305 is the answer to that equation
