D = t multiplied by constant of variation so. constant of variation= d / t
constant of variation = 300 / 5 which is equal to 60
The correct answer is x=-8
Answer:
Step-by-step explanation:
The sample space should show all the possible outcomes.
The first option includes all 4 colors and both head and tails.
The second option is missing tails as an outcome.
The third option is missing blue.
The fourth option is missing tails.
So it must be the first one.
Let us assume that the F is the first angle, S is the second and T is the third angle.
We know that
- F + S + T = 180°
- S = F + 20°
- T = 2S
We can substitute the S and T values into F, In this case, we will say that:
F + F + 20° + 2 (F + 20°) = 180°
2F + 20° + 2F + 40° = 180°
4F + 60° = 180°
4F = 180° - 60°
F = 120 ÷ 4
∴ F = 30°
S = F + 20°
∴ S = 50°
T = 2S
∴ T = 100°
To make sure that we have worked this out correctly, the angles should add up to give us 180°
Therefore, 30° +50° + 100° = 180°
