The first answer is 80, and the second answer is still 65.5. Hope this helps!
Answer:
cos(∅) = 3/5
Step-by-step explanation:
cos(∅) = adjacent/hypotenuse
We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.
a² + b² = c²
4² + 3² = c²
√(4² + 3²) = c
c = 5 , this is our hypotenus
cos(∅) = adjacent/hypotenuse
cos(∅) = 3/5
<span>Well first this one you can just count which ones are 9 units away so it could be A becuase -4+-9=-13
Another is B because
-4+9=5
