-90° and 630°
_____
Angles are conventionally measured counterclockwise from the positive x-axis. The angle shown in the attachment is measured clockwise, so represents a <em>negative</em> 90° angle.
Answer:
528000 ft²
Step-by-step explanation:
The Pyramid Arena has a shape of a square pyramid. A square pyramid is a pyramid with a square base and the top point is directly above the center of the base. It consist of 5 faces (base and 4 triangles), 8 edges and 5 vertices.
Given:
length of base (b) = 600 ft and height of lateral face (h) = 440 ft.
Since the lateral faces are made of glass, the area of each lateral face is the same as the area of a triangle with base same as base length and height same as height of lateral face.
Therefore, area of each lateral face = 1/2 × b × h = 1/2 × 440 × 600 = 132000 ft²
The lateral faces are made almost completely of glass and they are 4 lateral faces, therefore the total area of the glass in the Pyramid Arena = 4 × 132000 ft² = 528000 ft²
The answer is 120 instead of 12 because 12 equals 7.2
<span>Seth travelled 1 mile in 57.1 seconds. Now, I hour = 60 minutes and 1 minute = 6-0 seconds. Thus, 1 hour = 3600 seconds. Thus, 1 mile/57.1 seconds = (1 mile/ 57.1 seconds)(3600 seconds/1 hour) = (3600/57.1) mile/hour ≈ 63.047 mile/hour.</span>
