The sides of a quadrilateral are in the ratio 1:2:3:6. The perimeter is 138 cm. Find the lengths of the sides.

11.5cm, 23cm, 34.5 cm, 69cm

Step-by-step explanation:

1+2+3+6=12

138/12=11.5

First side=11.5cm

Second side=11.5x2=23cm

Third side=11.5x3=34.5cm

Fourth side=11.5x6=69cm

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.
