The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3
Step-by-step explanation:
We can see in the diagram that the values of all sides are given. In case of trigonometric ratios, the side in front of angle under consideration is perpendicular and the side adjacent to angle is base.
In the given case, we have to find trigonometric ratios for angle B; So,
Base = a = 3
Perpendicular = b = 4
Hypotenuse = c = 5
Hence,
The ratios will be:
The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3

The answer i believe is 4000
Hi there. :)
I'll try to make this simpler for you.
Let's focus on the equation from left to right, to avoid clutter.
-4(3 * 1/2) = -4(1.5)
Now to the right.
+ 2(3) = + 6
Now combine!
-4(1.5) + 6 =
-6 + 6 = 0
The answer is 0.
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
