In ΔUVW, w = 3 inches, ∠W=23° and ∠U=73°. Find the length of u, to the nearest 10th of an inch.
kirza4 [7]

Answer:

<h2>7.4inches</h2>

Step-by-step explanation:

Check the attachment for the diagram. Sine rule will be used to get the unknown side of the triangle.

According to the rule;

\frac{u}{sinU} =  \frac{v}{sinV} = \frac{w}{sinW}\\\frac{u}{sinU} = \frac{w}{sinW}

Given w = 3 in, ∠W=23° and ∠U=73°, on substituting into the equation above to get u we have;

\frac{u}{sin73^{0} } = \frac{3}{sin23^{0} }\\usin23^{0} = 3sin73^{0}\\u = \frac{3sin73^{0} }{sin23^{0} }\\u = \frac{2.87}{0.39} \\u = 7.358\\u = 7.4in

The length of u is 7.4inches to nearest 10th of an inch

Which statement is correct?<br> A. <br> B. <br> C. <br> D.
geniusboy [140]

Answer:

B

Step-by-step explanation:

Answer:

B

Step by Step explanation:

So since the equation says that 8 is less than the square root for b, It is correct because the square root of 72 would be 8.48528137424. Which of course 8, is less than that. But it also says that the square root of 72 is less than 9. Which based on my calculations would be correct.
