Complementary angles = 90°
x= angle 1
(90-x)= angle 2
Subtract the two angles to get the difference between them (18°).
(90-x) - x= 18
combine like terms
90 - 2x= 18
subtract 90 from both sides
-2x= -72
divide both sides by -2
x= 36° angle 1
Substitute answer in to find angle 2:
=90 - x
=90 - 36
=54° angle 2
Hope this helps! :)
42:35 or if simplified 6:5
ANSWER
D.
EXPLANATION
The standard equation of the hyperbola is
We multiply through by 36 to obtain:
We now expand to get,
Expand :
To get the general form, we equate everything to zero to get,
The correct choice is D.
