Answer:
56.27 in
Step-by-step explanation:
You can determine the length of the missing side IH by using sine law.
In the form of a/sinA = b/sinB = c/sinC, you can substitute an angle and its corresponding side, which in this case is angle I and side i, and do so with the other angle, which is angle X and side x.
<u> 74 </u> = <u> IH </u>
sin97 sin49
after this, multiply both sides by sin49 to isolate side IH -
(sin49) x <u> 74 </u> = IH
sin97
now plug all the numbers into a calculator and you will get the answer, 56.26792; when rounded, it should be 56.27 in.
Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
