What is the length of the missing leg

a = 12 meters

Step-by-step explanation:

a^2+b^2=c^2 substitute the lengths in

a^2+9^2=15^2 simplify

a^2+81=225 subtract 81 from both sides

a^2=144 square root both sides

a=12

step-by-step explanation:

i dont get

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
