Angles 1 and 2 are complementary and congruent. What is the measure of angle 1

45 i think i dont know

Step-by-step explanation:

m

∠

2

=

x

holds true.

Complementary angles have a sum of

90

˚

. Thus, if

∠

1

and

∠

2

are complementary,

m

∠

1

+

m

∠

2

=

90

Substitute the equivalent forms of these angle measurements

(

x

,

x

)

.

x

+

x

=

90

Solve algebraically.

2

x

=

90

x

=

45

Each angle is

45

˚

.
