Step-by-step explanation:
Answer: 0, 4
Step-by-step explanation:
Answer:
116 and 64 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees so we can create the following equation and solve for x:
4x + 2x + 6 = 180
6x + 6 = 180
6x = 180 - 6 = 174
x = 174/6 = 29.
So the first angle is 4*29 = 116 degrees and the second is 2*29 + 6 = 64 degrees.
To confirm these results add them up: 116 + 64 = 180 degrees.
Factor using difference of cubes, and set each factor equal to 0.
x=(-3+3i\sqrt(3))/(4),(-3-3i\sqrt(3))/(4),(3)/(2)
Answer:
6 and 15
Step-by-step explanation:
n1 + n2 = 21
2(n1) + 3 = n2
n1 = 6
n2 = 15
6 + 15 = 21
