Answer:
Alternate interior angles are congruent so 3 = 6. 54 degrees
Step-by-step explanation:
multiply 4 by the cos(45)
4 x cos(45) = 2sqrt(2) approximately 2.828cm
so depending how you are supposed to answer, either 2 sqrt(2) or approximately 2.83 cm
Answer:
A. 1
Step-by-step explanation:
Following order of operations, you would multiply 4/3 and 3/5.
Once you do this, you will get 12/15, which you can simplify to 4/5
Then you add the 1/5 with the 4/5 and you will get 5/5, which is equivalent to 1
Since opposite angles of a cyclic quadrilateral are supplementary,
A= 180-101=79°
B= 180-68=112°
How I got my answer before was substitution!
