The slop of the line that is represented by the equation -5x + 2y = 10 is
Complementary angles sum to 90°. Supplementary angles sum to 180°.
Answer:
D
Step-by-step explanation:
Open circle means less than or greater than, and the dot is on -5, so the answer is greater than -5
Answer:
D.x = 6; m∠XOY = 18°
Step-by-step explanation:
Supplementary angles add to 180 and complementary angles add to 90
∠WOZ + ∠WOX = 180
108 + ∠WOX = 180
∠WOX + ∠XOY = 90
∠WOX + 3x = 90
∠WOX = 90 -3x
Replace WOX in the first equation
108 + ∠WOX = 180
108 + 90 -3x = 180
Combine like terms
198 -3x = 180
Subtract 198 from each side
-3x = 180-198
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
∠XOY = 3x = 3*6 = 18
It's C. move all terms to the left side and set equal to zero. then set each factor equal to zero.
