Use a variable (x) for the smallest angle (call it angle 1). Angle 1 = x The second angle is twice the smallest angle (2x) The largest angle is 6 times the smallest angle (6x) Take the sum of all three of those angles and make an equation, equal to 180. x + 2x + 6x = 180 9x = 180 (combined like terms) x = 20 (divide by 6) Angle 1 (x) = 20 Angle 2 (2x) = 40 Angle 3 (6x) = 120
I believe the answer is 0.2105 and the error you made of saying 0.4209 was because you did a 2-PropZTest when this question seems to be asking for one proportion (not two). When the p value is greater than or less, use one-proportion, if it is "!=" not equal than it is two-proportion. Please let me know if this was correct.
Answer:
yES 2:3
Step-by-step explanation:
The sides are the same length
Answer: (0, 6)
Step-by-step explanation:
To find an ordered pair that is a solution, you have to pay attention to the shadings. Both equations have their own shadings. The shaded area that is a mix of blue and green is the solution that fits BOTH equations.
Looking at (0, 6) and (6, 0), you can see that (0, 6) is in the area where the shadings mix.
If you are wanting it simplified then the answer is x^2y^4
