Answer:

26 7/8

Step-by-step explanation:

17 1/2 - (-9 3/8)

Get a common denominator of 8

17 1/2*4/4 - -9 3/8

17 4/8  - -9 3/8

We know that subtracting a negative is adding

17 4/8 + 9 3/8

Add the whole numbers

17+9 = 26

Add the fractions

4/8+3/8 = 7/8

26 7/8

Use the Law of Cosines to find the missing angle. In triangle JKL, j=3in., k=4in., and l=2.89., find mJ
slega [8]
Using the law of cosine for Triangle KJL, we can write:

j^{2} = k^{2} + l^{2}-2(k)(l)cos(J)  \\  \\ 
2(k)(l)cos(J)=k^{2} + l^{2}- j^{2} \\  \\ 
cos(J)= \frac{k^{2} + l^{2}- j^{2}}{2(k)(l)}

Using the values of k,j and l, we can write:

cos(J)= \frac{ 4^{2} + (2.89)^{2} - 3^{2} }{2(4)(2.89)}  \\  \\ 
cos(J)= 0.664 \\  \\ 
J= cos^{-1}(0.664) \\  \\ 
J=48.39

Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer
