The length of a ruler is 170cm, if the ruler broke into four equal parts. what will be the sum of the length of three parts

127.5

Step-by-step explanation:

Multiply 170 by 0.75

127.5

3 divided by 4 = 0.75 = 3/4

0.75 x 170 = 127.5

or

170/1 x 3/4 = 510/4 = 127 1/2

1/2 = 0.5 = 1 divided by 2

127 + 0.5 = 127.5

127.5 is the answer

Hope this helps

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.

what level of math? also i don't need to be paid if i can you.
