Find the length of GV¯¯¯¯¯¯¯¯ A. 43.92 B. 33.1 C. 41.45 D. 68.87
ValentinkaMS [17]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find GV

To find GV we use cosine

cos∅ = adjacent / hypotenuse

From the question

GV is the adjacent

GC is the hypotenuse

So we have

<h3>\cos(37)  =  \frac{GV}{GC}</h3>

GC = 55°

<h3 /><h3>GV</h3><h3>\cos(37)  =  \frac{GV}{55}</h3><h3 />

GV = 55 cos 37

GV = 43.92495

We have the final answer as

<h3>GV = 43.92</h3>

Hope this helps you
