What single transformation maps ∆abc onto ∆a'b'c'? a. rotation 90° clockwise about the origin b. rotation 90° counterclockwise about the origin c. reflection across the x-axis d. reflection across the line y = x

my answer got deleted but it's a

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2

24

step-by-step explanation:

you just have to add the 15 + 9 to get 24

you do this bc you want to find the total of the whole line and those two numbers make up the line
