Find x in the triangle

Step-by-step explanation:

You have to solve this equation:

(8x - 3) + 37 + (5x - 10) = 180

then

13x +37 - 13 = 180

then

13x + 24 = 180

then

13x = 156

then

x = 156/13 = 12

check The attached picture.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
