x-7y=10 and 2x+14y=21

The answer to your question is: neither parallel nor perpendicular.

Step-by-step explanation:

Data

x - 7y = 10   ---(1)                and         2x + 14y = 21 (2)

First we need to clear y from two equations

7y = x -10                                              14y = -2x +21

y = x/7 - 10/7                                             y = -2/14 x + 21/14

                                                                 y = -1/7 x + 3/2

slope = 1/7                                               slope = -1/7

They are neither parallel nor perpendicular, if they were parallel the slopes will be the same, if they were perpendicular they would have inverse values.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
