Anson estimated he would need 17 hours to complete his science project. He actually needed 19 1 2 19 1 2 hours. What was his per

satela [25.4K]

Answer:

The answer is B. 14.7%.

Step-by-step explanation:

Given:

Estimated time need to complete project $17h$ .

Actually time needed $19\frac{1}{2}h$ = $\frac{39}{2}$ h.

Difference between the time $ET-AT$ = $\frac{39}{2}- 17\\=\frac{39}{2} -\frac{34}{2}\\ =\frac{5}{2}$ $=2.5h$ .

So, the percentage error is $\frac{2.5}{17}\times100\\ =\frac{250}{17} \\=14.70%$ .

Therefore, the answer is B. 14.7%.

Since you have the 42-deg angle and the length of the opposite side, 31, you can use the Law of Sines.

$\dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C}$

We will use the law of sines first to find x.

Once we know x, we can find the angle opposite y.

Then we can find y.

$\dfrac{31}{\sin 42^\circ} = \dfrac{37}{\sin x}$

$\sin x = \dfrac{37\sin 42^\circ}{31}$

$\sin x = 0.798639$

$x = \sin^{-1} 0.798639 = 53^\circ$

Let z = the angle opposite y.

z + 42 + 53 = 180

z = 85

$\dfrac{31}{\sin 42^\circ} = \dfrac{y}{\sin 85^\circ}$

$y = \dfrac{31 \sin 85^\circ}{\sin 42^\circ}$

$y = 46.2$
