#x=65 degrees#

Explanation:

Two angles are complementary when they add to 90 degrees.
Let "c" be the complementary angle.

#x+c=90#

The angle X is 15 more than (means "plus") than 2 times the complement

#x=2c+15#

Substitute

#[2c+15] + c=90#

#3c+15=90#

#3c+15-15=90-15#

#3c=75#

#(3c)/3=75/3#

#c=25#

Substitute into original formula
#x+25=90#
#x+25-25=90-25#
#x=65#
