Answer:


Step-by-step explanation:
Given
The attached triangle
Required
Solve for x
Considering angle 45 degrees, we have:
--- cosine formula i.e. adj/hyp
Solve for y

In radical form, we have:



To solve for x, we make use of Pythagoras theorem


Substitute for y


Collect like terms


Solve for x

Answer:
y=x
Step-by-step explanation:
Something that would create a direct proportionality is y=x because both of them are in an equation which means they are directly proportional
C 28.84 just multiply 38.45 by .25 then you should get 9.6125 you subtract 38.45 by 9.6125 and get 28.84
Check the picture below.
notice the solid circle at -4 and 3, since it includes those points.
also notice the dashed line, though the lines keeps on going those ways, is not included in the piece-wise, since it's not part fo the domain or constraints.
Answer:
109.5
Step-by-step explanation:
4 sides equals 360 degrees. 360 minus 96 and 45 is 219. divide 219 by 2 and boom theres your answer.
