The combined area of two squares is 45 square cm. each side of one square is twice as long as the side of the other square. what is the length of each side of the larger square?

L=6 cm l=3

Step-by-step explanation:

x+y=45

L=2l

Big Square Area

L*L=x

Little Square

l*l=y

Substituting

(L*L)+(l*l)=45

(2l*2l)+(l*l)=45

(4l^2)+(l^2)=45

5l^2=45

l^2=45/5

l^2=9

l=sqrt(9)

l=3

L=2(3)

L=6

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
