-2x + 3y = -21
-2x = -21 - 3y
-2x + 21 = -3y
-3y = -2x + 21
3y = 2x - 21
y = 2/3x - 7
Slope = 2/3
Y-intercept = -7.
-2x = -21 - 3y
-2x + 21 = -3y
-3y = -2x + 21
3y = 2x - 21
y = 2/3x - 7
Slope = 2/3
Y-intercept = -7.

-2x + 3y = -21
-2x = -21 - 3y
-2x + 21 = -3y
-3y = -2x + 21
3y = 2x - 21
y = 2/3x - 7
Slope = 2/3
Y-intercept = -7.
-2x = -21 - 3y
-2x + 21 = -3y
-3y = -2x + 21
3y = 2x - 21
y = 2/3x - 7
Slope = 2/3
Y-intercept = -7.

Step-by-step explanation:
Let the missing angle be x then .,
81 + 62 + x = 180 (being sum of angles of triangle )
143 + x = 180
x = 180 - 143
x = 37
Therefore the missing angle is 37
