If t is the midpoint of modifying above upper s upper u with bar, what are st, tu, and su?
a. st = 20, tu = 20, and su = 40
b. st = 80, tu = 80, and su = 160
c. st = 16, tu = 80, and su = 160
d. st = 102, tu = 102, and su = 204

how are the two angles below related? drawing not to scale.
a. supplementary
b. adjacent
c. complementary
d. vertical

n

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
