Question 319285
<font face="Garamond" size="+2">


The sum of an angle and its complement is *[tex \Large 90^\circ]


Let *[tex \Large x] represent the angle.  Then the complement of the angle must be  *[tex \Large 90\ -\ x].


Four times the complement is then:  *[tex \Large 4(90\ -\ x)]


25 degrees less than that is:  *[tex \Large 4(90\ -\ x)\ -\ 25]


And that expression is equal to the angle, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ 4(90\ -\ x)\ -\ 25]


Solve for  *[tex \Large x]
