It would be A. You can find this out by using SOH CAH TOA,
SOH means sin= opposite/hypotenuse
CAH mean cos= adjacent/hypotenuse
TOA means tangent= opposite/adjacent
You would use CAH since you are trying to find cos∠C
You would have cos∠C=10/26.
26 is the hypotenuse since it is opposite the right angle and is the biggest side.
10 is the adjacent since it is right next to C
You would simplify this down to 5/13 by dividing by 2.
This gives you A.
b.) It ensures you will take the proper precautions when setting up your experiment.

Step-by-step explanation:</h3>
<em>Question 4</em><em>:</em>
Just take the first number 322 and plug in the choices.
At the end the only one that will finish with all exactly like the pattern is ÷10.
<em>Question</em><em> </em><em>5</em><em>:</em>
We know Logan's watch is still under warranty because,
1 week = 7 days.
6 weeks × 7 days = 42 days
But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.
