Answer 2

#45˚#

Congruent angles have the same measurement (are the same size). If #angle1congangle2#, then

#mangle1=x#
#mangle2=x#

holds true.

Complementary angles have a sum of #90˚#. Thus, if #angle1# and #angle2# are complementary,

#mangle1+mangle2=90#

Substitute the equivalent forms of these angle measurements #(x,x)#.

#x+x=90#

Solve algebraically.

#2x=90#
#x=45#

Each angle is #45˚#.

Since complementary angles' sum is #90˚#, they form a right angle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
