No, she didn’t use the entire fraction as the base, so wrote the expanded form wrongly.
and I know this cuz I took the test

9514 1404 393
Answer:
(c) 14.5 cm
Step-by-step explanation:
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(65°) = BC/BA
BC = BA·sin(65°) ≈ (16 cm)·0.9063 ≈ 14.501 cm
BC ≈ 14.5 cm

<em>Additional comment</em>
As is often the case, a simple estimate is all that is needed to identify the correct answer choice.
You only need to know how the long side of a right triangle compares to the others. In an isosceles right triangle, both legs are √2/2 ≈ 0.71 times the hypotenuse. The long side of a right triangle will never be shorter than that. This means the long side must be greater than about 11.2, and cannot be greater than 16. There is only one answer choice in that range.
Answer:
he earns $15 an hour. the equation is 12h=t
Step-by-step explanation:
you can make the equation 180=12x where x equals the amount per hour
divide 12 by both sides and you get x=15 which means he makes 15 dollars an hour
