Two words. The input and the output determine this
Answer:
A
Step-by-step explanation:
two complementary that have the same measure angels always equals 90
12=2.55 how about 8
8 x 2.55 divided by 12=$1.7
The total measure of the interior angles of a quadrilateral is 360 degrees
you are given 57, 65, 118
That is 240
to solve for the last angle
360-240
120
The exterior angle of a D would be the number that you add that will make it 180 degrees.
meaning 180-120 is
The exterior angle of angle D is 60 degrees.
Hope this helps
