The theorem tells you angles complementary to the same angle are congruent. Both 4 and 1 are complementary to 5, so 4 and 1 are congruent.
The angle congruent to 4 is 1.
Answer:
all work is shown and pictured
It's C.
multiply by 3
x = 4, y = 4x3 = 12
x = 5, y = 5x3 =15
x = 6, y = 6x3 =18
I don't know how to explain but the answer is 2.4.
5.8/ sqrt 80=0.648 I think you are asking for the standard margin
Hope this works
