Use the law of cosines to find the value of cos theta. round your answer to two decimal places

REY [17]

Answer:

The correct answer option is B. 0.21.

Step-by-step explanation:

We are to find the value of $cos \theta$ using the law of cosines.

We know that the formula of the cosine rule is given by:

$c ^ 2 = a ^ 2 + b ^ 2 - 2 a b cos C$

So substituting the given values in the above formula:

$10.9 ^ 2 = 5.8 ^ 2 + 10.5 ^ 2 - 2 (5.8) (10.5) cos C$

$118.81=33.64+110.25-121.8cosC$

$118.81 - (33.64+110.25) = -121.8cosC$

$118.81-143.86=-121.8cosC$

$cosC=\frac{-25.05}{-121.8}$

cos C = 0.21

Maximal use of bezels, gradients, and drop shadows make an interface highly user friendly True False

tigry1 [53]

Bezels, gradients, and drop shadows can make an interface user-friendly if used wisely and minimally. If too much, the interface can be distracting. The problem used the term "maximal." This means that the bezels, gradients, and drop shadows are excessively used in an interface. So, the answer to this question is
FALSE
Using too much image effects can make an interface not user-friendly.
