It depends on what you know about the triangle.
The usual formula taught in Geometry class is
.. A = (1/2)*b*h
where b is the length of the base, and h is the height (altitude)
If you know two sides (a and b) and the angle between them,
.. A = (1/2)*a*b*sin(θ)
If you know three sides (a, b, c) then Heron's formula applies:
.. s = (a+b+c)/2
.. A = √(s*(s -a)*(s -b)*(s -c))
If you know two sides and an angle not between them, then you can use the Law of Sines to find the angle between them and use the formula above. In some of these cases, the triangle may be incompletely specified, so there may be two different legitimate values for the area.
Answer:
two
Step-by-step explanation:
Answer:
30$ for a pack of 15
Step-by-step explanation:
12$ ÷ 6 to get the price for 1 can, then use that to multiply by 15 to get how much 15 cans cost.
The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively
<h3>Horizontal and Vertical components of vectors</h3>
For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.
By convention, the horizontal, Vx and vertical components, Vy are as follows;
- Vx = V cos π
- Vy = V sin π
where π = angle of inclination to the horizontal.
Hence,
- Vx = 881 × cos55° = 505.32 ft/s
- Vy = 881 × sin55° = 721.57 ft/s
