Midpoint coordinates= ((x1+x2)/2 , (y1+y2)/2)
=((0+-4)/2 , ( 4+-12)/2)
= (-2, -8)
The answer to that would be 18
5 = side a
3 = side c
angle B = 62 degrees
JK is side b
<span><span>Use the Law of Cosines to find the length of side b.</span><span>
<span>b^2 = </span><span>a^2 + c^2 − 2ac cos(B)</span></span><span> <span>
b^2 = </span><span>(5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)</span></span><span> <span>
b^2 = </span>(25 + 9) − 30 x 0.469</span><span> <span>
b^2 = </span>34 - 30 x 0.469</span><span> <span>
b^2 = </span>34 - 14.084</span><span> <span>
b^2 = </span>19.916</span><span>
b = √19.916</span><span>
b = 4.463
Rounded to the nearest tenth is 4.5 mm.
Hope this helps!</span></span>
