First of all, you need to recognize that ∠GHE and ∠AHD are "vertical" angles, so they are equal.
Then, you need to recognize that ∠AHD and ∠AHK are complementary angles.
Then you have
.. ∠AHD +∠AHK = 90
.. ∠GHE +∠AHK = 90
.. (60 -x) +(2x -6) = 90
Now, you have a linear equation in x that is easily solved.
.. x +54 = 90 . . . . . collect terms
.. x = 36 . . . . . . . . . subtract 54 . . . . . . . . . matches selection B*
___
* except that the answer is actually 36, not 36°. The variable x is used in an expression to which the units "degrees" are attached. x is a pure number; x° is 36°.
Answer:
The independent variable in this experiment was the attention students gets from the teacher
Step-by-step explanation:
An independent variables are variables in maths, statistics and experimental sciences that stands alone and isn't affected by the other variables you are trying to measure.
Answer:
choice a.) 11m
Step-by-step explanation:
2(5m) + m = 10m + m = 11m
Answer:
it looks like it is completely factored out to me at least there is a high possibility I am wrong because that looks complicated I wish I could help
