In the figure, what is the value of x? Now subtract the blue rectangle from this. Length of diameter of a semicircle = 150 m, So radius of the semicircle = 150/ 2 = 75m. Since the height of our object is \(50\) meters and the height of the semicircle part, our radius, is \(10\) meters, that means the length of our rectangle is \(50\) meters-\(10\) meters, which is \(40\) meters! So it makes sense to write it as an approximation. WebAccording to this diagram, what is tan 67? Give your answer in 8,400=140*width. What is the value of x?
