The Duquesne Incline in Pittsburgh, Pennsylvania, has an angle of elevation of 30º. The track has a length of about 800 feet. Fi
Roman55 [17]

Answer:

The height of the incline is 462 feet

Step-by-step explanation:

Here, we are asked to calculate height, given the angle of elevation.

When we talk about angle of elevation, we refer to the observation angle that we have when we look up from a position which is at the base.

Please check attachment for diagrammatic representation of the question terms.

From the attachment, we can see that we have a right angled triangle. We are asked to calculate the opposite given the adjacent.

Thus the trigonometric identity to use is the Tangent

Tan 30 = h/800

h = 800 * Tan 30 = 461.88 approximately 462 feet

A triangle has an area of 125 square inches. The height of the triangle is 8 inches. Which equation
Free_Kalibri [48]

Answer:

(125*2)/8=b

Step-by-step explanation:

The way to find the area of a triangle is to multiply height and width then divide by two and 125 is the area. Then that means 125=250/2.

Since the height is 8 we can make the equation (125*2)/8.

Hopefully that was helpful and made sense.
