Centimeters are more accurate.
Answer:
m = −3
Step-by-step explanation:
Use the slope formula to find the slope m
.
We can find m∠BCD like follows: m∠BCD=90°-45°=45<span>°
Now, m</span><span>∠DBC= 180°-(90°+45°)=45°
Remember that </span>
, so
We know that hypotenuse= BC= 3in and
=∠DBC)=45°, so replacing the values we get:
We can conclude that the segment CD is 2.12 in
5. The answer is D
because it says no more than 160 so it's possible to be equal to 160.
6.
So the answer is A
