what's the angle? I don't know if this question is solvable without the base angle.

YRJ8498:

(90 - x) is the complement of the angle x. Therefore, the angle four times its complement is 72 degrees.

surjithayer:

x=4(90-x) x=360-4x x+4x=360 5x=360 x=360/5=?

surjithayer:

correct

surjithayer:

x=72
