Xand y intercept equations x +2y =18

(0,9) and (18,0)

Step-by-step explanation:

To find the x-intercept, set y = 0.  Note how this equation x + 2y = 18 becomes x = 18.  Thus, the x-intercept is (18,0).

To find the y-intercept, set x = 0.  Then 2y = 18, and y = 9.  The y-intercept is (0,9).

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
