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:
as an instinct i thought that i should multiply 11 and 5, so im saying 55 different selections
Step-by-step explanation:
sorry if im wrong
Answer:
1584 square kilometers.
Step-by-step explanation:
Here's the function I use.
a= starting amount
r= rate
t= years
First step:
Second step:
Third step: =1583.72164269
Fourth step: Round to the nearest square kilometer. Since 1583.7 is closer to 1584, you must round up.
Fifth step: The final answer is
Hope this helps and stay during these crucial times. We'll get through this!
