Answer:
131 and 49
Step-by-step explanation:
Supplementary angle means 180° when all angles are added together.
First angle: (x + 82)
Second angle: x
(x + 82) + x = 180
2x + 82 = 180
2x = 98
x = 49
First angle: 49 + 82 = 131°
Second angle: 49°
Answer:
Step-by-step explanation:
Answer:
4x-2y =42 is the required equation
Step-by-step explanation:
given equation is,
4x-2y -7=0---------eqn1
parallel equation of given equation is
4x -2y+k =0-------eqn 2
now passing it through (9,-3), we get,
4×9 + 2×3 +k = 0
or,36+6+k =0
or,42+k =0
or, k= -42
putting the value of k in eqn2
4x-2y - 42=0
4x-2y = 42
